As a warrior tank you dont replace anything before Kara, maybe some trinkets/rings/your neck.
So its most likley a big difference between classes, think rogues didnt replace most things until they were ether doing heroic dungeons or raids (and Kara you can do before going into a single heroic dungeon)
Only fools prefer TBC over vanilla.
Only fools prefer vanilla over TBC.
I guess Iām a double fool then. I prefer both of them. Over WotLK.
And thatĀ“s why when it was actually still current (and challenging) content everybody and their mother, including high end raiders, complained about Years worth of effort being nullified in under 2 hours? 
That was the whole reason they overworked their approach to item scaling in Wrath so that many if not most of us were still wearing T6 when we dinged 80, or our t10.5 until 85 in cataā¦
IIRC Warriors were the only ones that actively kept their Tier 3, literally almost everyone else replaced it with questing greens because they had almost twice the stats.
This is entirely correct, in modern expansions such as TWW if you have 515+ DF gear you will be wearing that until 69 or 70 when higher itemlevel gear actually starts to drop, as opposed to replacing it with greens that have twice the stats 10 minutes after entering the new zone. 
Unless ofc they have done significant changes to the itemlevels and corresponding statsā¦ I havenāt touched TBC classic and donĀ“t plan to, as I have good memories that I would like to preserve and not have

You are exaggerating quiet a lot, casters, who are most impacted by this, still only start replacing enchanted T3 with blues around level 65, specifically socketed quest and boss rewards from Mana tombs and Auchenai crypts. Then it speeds up with elite quest rewards and drops from lvl 68+ normal dungeons, steam vaults, shatered halls, bot and mech etc.
The āgreens you get in first 10 minā will indeed replace all old world levelling gear, as in stuff you go into dark portal if you hit it the moment you ding 58, yes.
I think that the most important thing is to find a guild. Solo wow experience is miserable.
No? The only thing they have is more stamina and armor compared to T3. No green during TBC questing has the stats that T3 have, not to mention the set bonuses.
The whole ālast expansion epics get replaced by questing greensā was never true until cata.
This literally never happened when you had epics from the previous expansionās last raid on, no matter if it was LFR or HC gear.
Even Molten Core epics were not replaced until almost halfway to 70, what does that say about T3?
Exactly. As a healer I didnāt even need to replace 80% of my T3 until I got to 70 and could buy badge gear or run kara.
I am playing anniversary very casually right now, not even a single toon at 60.
I plan to level about 3 chars to 60, very casually, hoping from one to the other making use of rested XP.
To prepare for TBC i would
Hi Iāll actually answer your question and not moan.
I plan to get a full quest log to hand in after tbc launches, make friends and collect gold.
Donāt forget RL preparations as they are at least equally important.
For instance, stock up food and coffee. If you flavour your coffee, prefer canned over fresh milk. In general, buy durable canned or frozen food.
Establish a form of continuity management, i.e. buy a second micro wave. Maybe even a generator would make sense to counter power outage.
Ensure a good supply on essentials like tobacco, alcohol and energy drinks.
I plan with friend to level mage on separate accountā¦you know to be ready for Slave Pens and boost our mains ,because i believe leveling via questing will be near impossible in begining on crowded Mega server on such a small Outland.
Yeah, TBC is the one expansion where levelling via dungeons is massively advantageous and all but officially encouraged by the game.
You can run each dungeon cluster until revered with itās corresponding faction, then move on to the next one. This gives you very nice rep rewards and preserves all the quests to be done for increased gold reward at 70.
Furthermore, all quests in Outland except like 3 in Hellfire are still green at 70 and give full reward of rep at revered, boosting you further to exalted for less heroic farm.
Iād go as far as to say itās foolish to not level via dungeon spam even if you were alone in the world for easy tags. And doing all of Outland quests at 70 gives you more than enough gold to buy epic flying. The more I think about it the more I realize doing quests in TBC levelling is a massive noob trap.
You can easily get to 65 lvl in Azeroth and many people donāt know that , which i did back in the TBCC and then get to 70 in OL instances ā¦after that month or so when situation is little bit better and less crowded, you can start doing quests for gold. I believe around 5k gold is amount you get from finishing all quests in OL. With my mage i had around 2 - 3K gold just by leveling in Slave Pens and vendoring stuff from there and when i did all OL quests i had around 8k gold or even more.
Be level 60 by the time TBC launches. Thatās all the preparing you need.
having some gold saved up doesnāt hurt
save up some free days to use them to level up and grind all those reputations
I canāt prepare ā¦ I want to play a Draenei Paladin on HC!
Just give HC progression to TBC as well.
Still no preparation needed other than to wait ā¦ only maybe reserve names.
Why so busy?
This is nonsense - as is the failure of some players in this thread to grasp the reality (which is that not everyone will walk into bc in full t3 bis omfgimba).
Molten Core epics ARE easily replaced with greens.
This is from a quest in Hellfire Peninsula, the starting zone. I challenge you to come up with a better caster weapon from Molten Core. Because Azuresong Mageblade and the Staff of Dominance are nowhere near in terms of damage (and you might want to check the stamina/intellect too).
Once again, nonsense.
If I recall correctly, this is the best healing weapon in Naxx:
Some would argue that the NORMAL mechanar drops are better:
For heroics drops youāve got
Itās the same with the rest of the items.
Even where those items are CLOSE in terms of pure +healing (which isnāt the case for anything important, anyway), you NEED the BC items for stats (stamina/intellect) unless you want to get one-shot or run oom in the first heroic.
Keep in mind that this comparison is made in relation to KT loot, but in reality, most people will not walk into TBC decked out in late-Naxx gear, but rather MC/BWLā¦and those will be replaced by the time theyāre done with Hellfire Peninsula with the odd exception here and there (Neltharionās Tear would be kept, for example).
