I quit last january after 10 years when I realized WoD was just the beginning of a new wave of WoW development so literally nothing at this point could bring me back because the game I loved is never going to return.
Blizzard has this lovely habit of reinventing the wheel every expansion and the game just fucking changes for the worse every time. The new direction they've taken PvP in since MoP has actually just made it unplayable.
They strip every non traditional play style away from every single class. The hybrid tax may no longer be there but now it's more of a penalty where you can't access even 10% of your other specs potential tool kit, so basically you're forced to only do your assigned role.
The game is a fucking shell of its former self. If you go to a private server you realize the reason people interacted with each other was because while you could solo stuff just fine, you went at the slowest pace possible. After most engagements you had to stop and eat or drink because natural regen was non existent and personal heals were few and far between unless you had a healing spec available to you.
So people were forced to cooperate to get things done efficiently. Now people are forced to cooperate because blizzard says so, the end result if you have a group of 5 with each person just basically playing a single player game as if the other 4 players were just bots.
Classes are so fucking streamlined it hurts to see. Every DPS spec with like 2 or so exceptions plays the same. You have a spam attack, a filler, a resource builder, a resource dump, a buff to manage and a debuff to manage. That's literally every fucking spec. Tanks are also basically on auto pilot all you need to worry about is positioning and be aware fo the fight mechanics, healers also all work about the same, support cool downs, emergency cool down, big raid cool down, fast expensive heal, slow efficient heal, slow expensive huge heal. Except some have HoTs instead of casts.
The new content for legion is just so blah, they dont really address any of the core issues the game is experiencing. The fact that pvp is getting its own separate line of progression frustrates the hell out of me because blizzards idea of balancing pvp is always the same - give them more HP, reduce burst and reduce CC.
Also the game runs like shit and is graphically a huge cluster fuck. Models and textures from 2004 mixed with higher rez and higher poly assets from 2011 and on wards is just a disgusting sight to behold.
The content trickle is awful, WoD was essentially a 1 patch expansion. Because High maul and BRF were the same tier, and the only major patch before the release of the final raid was the twitter integration patch + selfie business. WoW expansions always ends the same, with 10 months of nothing new.
Considering it's blizzards prime cash cow they should really care more about it than they actually do. But they never will and even if they say they will it won't last for long.
I've been burned by this shitty dev team too many times to ever give them the benefit of the doubt again.
And yes I am very bitter when it comes to this game.
