It doesnt make sense, blizzard been doing everything to help pvp
they:
Its doesnt make sense why no ones is playing, they tried nothing and are all out of ideas
Season is still 3 months
Makes perfect sense. They made most brackets limited/ deflated making it harder to get anything. Its christmas so people are busy and I imagine when mmr is more inflated more people will play.
more a design issue than balance imo, its hard to enjoy the classes when there is this much ccs/micro cc, interrupts, and im assuming melee players have similiar issues, but i still think cc/micro cc and interrupts (and i donât mean the literal interrupt, i mean, WAYS TO STOP AN ACTION/CAST, LIKE, SHADOWMELD, FEIGNDEATH, or even blind/ring of peace, just to stop that 1 sec of sheep)
HC is the current big thing. Just wait a month when race is over and most people are 60 and watch retail slowly come back to life.
I think itâs a balance problem, and also the stupid design that PVE and PVP sets require the same currency. I like both, but i wonât waste the silk for PVP because iâm already playing a class that is really bad in PVP so why bother.
You are wrong. PvP declining in retail has nothing to do with hardcore classic. Retail has not lost players to hardcore classic. Most people that play on hardcore are from other classics such as sod, wotlk, and classic.
âPvP numbers decline for no reasonâ.
âŚthereâs an abundance of reasons 
I think it has something to do with the social contract. A lot of players getting their account banned lately.
Iâll never get why big pvp player all of a sudden go play a crap old version of a game to bash mob 24/7 with 2 ability in their bar.
But I guess it is what it is.
Of course nobody plays TWW PvP.
It is:
uninspired (hero talents barely change anything for most specs)
frustrating (MMR; toxic class design e.g. Frostbite)
badly balanced (duo blitz queuing; too many heal specs in âgarbageâ-tier).
and
All things a competent dev team could have prevented.
take your pick
I agree that the mount and illusion is garbage. However, the PvP devs have been quite competent this expansion. They have put a lot of effort into PvP to make it enjoyable for us. They have done the most for PvP this expansion of all expansions since MoP.
What they have achieved is;
*Bring PvE players into the PvP scene and also new players.
*Adding a new fun PvP mode (blitz).
*They listened to the playerbase and injected lots of MMR.
*All rewards are easy obtainable. Yes and that includes the gladiator mount. All youâve got to do is to que up, play good and get to 2.4k.
*Easy to gear your character and alts. It has never been so easy. You can even transfer honor and conquest between your characters. Can it be better?!
PvP is heaven right now.
*Frequent class balance.
We PvP players have it so good that PvE players have started to complain about this to Blizzard on a massive scale.
We should be thankful for what we have.
PvP just isnât good.
Bad balance, very bad pacing, endless CC chains and micro CCs, MMR system, queues, cheating, wintrading, premades.
We have had class balance almost every second week. You call that bad balance? 
Bad pacing? What do you mean? CC have to exist for a reason or otherwise healers would have had an upper hand by healing large amounts without getting disrupted. Trust me, CC is in the game for a good reason.
Most here think that wintrading happens all the time which is false. Wintrading is a rare thing. If it happens its probably 2 friends that got put in the same solo lobby and lets say one of them is at 2380 rating and tells the other friend to let him win to get 2.4k. Thats what I can think of right now. However, organized wintrading do not exist.
Cheating is also something of the past. Kick bots and stuff is non-existent because Blizzard has a superior system that prevents those things.
good joke
current pvp is as good as the current looking Glad Mount.
Multiple reasons fill this cup. For me tho, balance problems in PvP take the cake.
Certain spec favouritism and on the other hand resentment of other ones is frustrating.
Congrats youâve mainly listed the reasons why pvp will continue to die. You can stop kissing Blizzards shoe now.
What exactly do we have?
2s is dead thanks to shuffle
3s is dead thanks to them releasing the worst glad mount in history. Iâm sure blizzard made it bad on purpose just to make people flock to blitz.
Shuffle is dead thanks to blitz giving out even more free rewards thus making any other bracket obsolete.
Blitz is also dying because at the end of the day itâs just random bgs.
I actually decided to look you up and find out why youâre simping blizzard so much.
No surprise youâre exactly the player im talking about youâve only achieved 2.4 in sls2 and ofc with the release of the meme bracket blitz
Like seriously stop crying about balance, as a league of legends player myself, where like 30% of champions are absolutely useless garbage , I can say wow have decent balance.
On ANY spec you can find some success and rewards in some brackets.
Bad rewards? Lol has border around your account and crappy skin once per year, even far worse rewards than in wow. Micro cc? Lol has tons of micro cc, sometimes you die without pressing a single spell.
Real wow problem is that no one likes arena concept. Now arena elitists gonna come here and protect their pillow fighting, but talking to many players who quit wow into other pvp games it was all the same issue - they donât like blizzard pushing to play 3v3.
Plus no one wants to play wow itself because game is empty and has no content and there is nothing to do outside of queing pvp (too long cause of many game modes) or farming old content.
