Personally I think they removed too many things from endgame pvp without the proper attunement of other things. I haven't played endgame pvp since the 2nd season of Legion or something like that, but it felt like the game had become even more "rock, paper, siscors"-like than what it used to be. The skill ceilling has just completely collapsed. 2's seem to be one of the most affected brackets to these changes. 2's is just straight up cancer now. Even if the bracket didn't award you titles, it was still fun up till WoD/Legion.
I could just be burned out I guess, but I doubt it. WoD was bearable, but Legion just turned me off completely. And I play a lot of classes, so it's not that I don't seek variety. I just lost interest completely.
I also liked the fact that you could customize your characters prior to legion. For instance, mages could go haste for faster sheeps etc. or mastery for that huge ice bomb/icicles + ice lance nuke. You had ways to tailor towards a playstyle. That's gone too now...
