This is a much much bigger question than it seems. It’s more like a philosophical question. What is Classic and what do we want. Throw in some slippery slope fallacies and a bunch of opinions and feeling. It’s not a small topic.
Personally I want to adapt to Vanilla and not the other way around. With the exception to fixing game breaking bugs and exploits.
Cool story OP, now try being a class who can’t go into stealth form.
if you lose your world buffs as a druid or a rogue, its a l2p issue.
i get all of the world buffs (including Darkmoon buff) every week for every single raid, yes even the 20-mans, and since i started raiding i think i’ve lost my buffs or gotten ganked a total of 3 times.
its a matter of learning from your mistakes.
if you are afraid of losing DMT buffs and songflower, ask for a portal to a different capitol city or use your HS and log out in the corner of the inn, out of sight of those pesky shamans/priests who are outside the inn scouting for people to dispel.
make use of summons. i’m sure you know at least one person who has multiple accounts. in my case i got a buddy who can summon me to all the key locations so that i can safe time on the buffs and get to raid without risking being caught on the way there.
i don’t use more than one account, but considering the sheer lucrative incentive, i am considering making 2-3 more, just to plant clickers in DM, Felwood, Yojamba, Elwynn Forest and Crossroads (not to mention in front of the raids like BWL, AQ and ZG).
and if that’s not incentive enough, then just consider for a couple of minutes how much gold i could be making simply selling summons. even when i play my alt warlock i often get whispers from people offering up to 20-30 gold for a mere songflower summon - money i have been unable to cash in on, as i don’t have 2 more accounts with clickers to make this possible.
but if i had, then not only will i be able to summon people on my own, but i would (in case of 3 extra accounts) be able to summon myself anywhere in the world and collect all my worldbuffs in an hour or less.
as you can probably tell, i’ve dealt with dispellers many times, but i’ve also gotten much better at avoiding their shenanigans - and that’s WITHOUT the ability to simply stealth and avoid them completely, something you have the ability to do.
bottomline: stop QQ and git gud.
EDIT: ahh hold on, you’re not a druid, that’s just your anon avatar that you use to trollpost or avoid being recognized for whatever reason. well, suddenly i care a whole lot less about your problems m8.
If you don’t want to be dispelled, don’t take world buffs, or goto PvE servers.
If you are a good players, you will never be dispelled. If you are dispelled, it’s always your fault.
If you don’t like world buffs, play without, but don’t force me to play like you.
If you are not good enough to take it, and your guild don’t prioritize yourself about items or spots in raids for that reason, you can find another guilds. No one like to play with players that don’t share the same mindset, but at the end it’s normal to prio items and spots for people that are dedicated into the game.
My 5 tips to avoid dispell :
Subscribe a second WoW account to make a character on opposite faction and scout with /who command before Mage port. Never take a portal without scouting before.
Put your hearthstone in empty area where nobody will dedicate time to dispell/kill yourself (Desolace, Arathi, …).
Tell all your guildmate to create a Warlock level 20 and multiple clickers. Put them everywhere (BB, Orgri/SW, AQ40 portal, Felwood, Dire Maul, Thunder bluff/Elwynn for Darkmoon Fair, …).
Prepare your raids consumables way before the raids, I often saw people running into auction house/mailbox/bank in city with full world buff and then they cry like spergs because they died.
Try to find secret/hidden spot 
.
In my opinion, the only “guy” that are legitimate to cry about getting dispelled are Alliance players that take Rend, because it’s very hard to tell if Orgrimmar and Barrens are safe or not for them, and it’s easy to make trap for opponent.
What you say is all true, but is not a good enough reason to change the game. If we apply that logic to all imperfections of the game very soon we won’t have classic anymore.
World buffs are optional, there are pve servers etc… Etc… There are multiple solutions available without changing the old game mechanics.
what is with all the tears?
You dont even need wbuffs to clear content. If you cant clear current content without? You are screwed anyways.
This , buy 3 more subs to move yourself around the world and organize your warchieff blessing , this is just terrible , might as well start multiboxing to lock down zones for herbs , so playing your main is only raidlogin , that is just terrible game design
How can you tell, you are only level 10!
i’d consider it a smart way to circumvent losing world buffs and make ez money, but hey, if those 27 extra euros per month ruins your real life economy, then by all means don’t take my advice.
ironically, considering current gold price to IRL currency, you’d easily make that money back in raw gold in game three-five times over before the month is out, solely by selling summons. im not saying you should sell gold or anything, but if the gold prices are anything to go by, then you’re actually making a profit by investing into more accounts.
Actually if you remember how retail Vanilla was it was pretty much no world buffs to raids.
No one had those all the time (population smaller, head turnins were often random)…
Most allies spent time in Ironforge since it was the only city with AH in the beginning… so no random Rallying cry.
Really I remember only 1 MC raid we got some buffs to make it fast and see how quick we can do it.
Then next time probably something in Naxxramas. Everything else no world buffs…
Do you realize you are promoting here selling gold for real life money , and why multiboxing needs to be banned and put into breaking TOS your statement “ironically, considering current gold price to IRL currency, you’d easily make that money back in raw gold in game three-five times over before the month is out” you are saying sell gold for real life money
No world buffs in raids should be since Clasic release… now after 13 months of world buffs abuse Blizzard so much ruined game that is not possible to repair anymore…
Real Classic Vanilla is dead, we got only LFR version of classic for casuals and tryharders…
My only hope is in TBC even im afraid Blizzard will nerf it too if they use 2.4.3 patch without any fix and un-nerfs
False!
World Buffs was pretty much part of the game back in vanilla in same way they are used now, we were just not as eager to pop them everyday 24/7.
We were not that stupid that we didnt know what sort of impact Wbuffs had on the game. It made it easier and was required by many guilds to come fully buffed to raid. Maybe not on your server, but stop saying that Wbuffs was not a thing in the past. It’s just plain false statement.
What exactly did they ruin? The game was made 15 years ago, with totally different mindset on how players play games. Now you play a copy of that game.
I’m jumping right into the fryingpan by saying this, but : I’m pretty certain the community have done their share ammount of work to “ruin” classic with exploits, cheats, excessive botting and so on.
The easiest thing in the world is blaming everyone else without any self-criticism.
To be fair, even without exploits/cheats/excessive botting and whatever had you, raids would have been meh by today’s standards regardless.
And no, not because “Bosses needed +100% extra health!” No matter how much health you give Ragnaros, it’s not gonna turn into a fight like Kael’thas. No matter how much health you give Nefarian, it’s not gonna turn into a fight like Illidan or Lich King. Classic fights are just boring mechanically wise, and no amount of HP/dmg tweaking is gonna fix them.
Sounds like you need to find other people to play with, rather then keep doing what you dont wanna do.
World buffs are in no way required to clear content. It only speeds it up, nothing else.
So find better friends who get that, like minded people.
I have doubts 
I played Vanilla as well and can’t remember at all that we got wbuffs back then except Ony , which was more or less organized (but closer to less), and DMF when it was at our Capital. But we never got DMT or SF, HoH was mostly popped before we did ZG. And I was in a guild which cleared AQ (we went into Naxx a few times, I think we killed 1-2 bosses), so I must have been in one of the top guilds on my server.
Regarding the topic, there are also good guilds (everyting on farm) who raid without wbuffs, except in DMF weeks where they go for a speed run, which you could join if you dislike wbuff meta.
I vote for changing the mentality of the majority of players. So much toxic behaviorin wow now.
It would have been the best thing since the start of classic. The world buff just makes everything trivial, no wonder they aren’t allowed on retail anymore.
The whole classic is about toxicity tbh atleast on pvp realms. Everything you do is just to make the other side miserable, the bg farms, the world “pvp” fly/instance camping, the dispels etc. None of these give any rewards other than the feel that you just ruined something for someone or made them angry. But it was already visible in p2 and blizz did nothing because its mostly favoured the bigger playerbase.
