However, the issue in regards to PvP at least is in my opinion that the focus on Arena is what made PvP a lot worse.
Because everybody is forced into this cage match, you cannot pick your fights anymore and everybody needs to have a winning chance against everybody.
It's the infamous arms race some people talked about for years.
Class X is super immobile, mobile Class Y just kites it easily, therefore Class X seriously struggles in an Arena match where Class Y is present on the enemy team.
Now Class X gets some form of gapcloser, despite that the class shouldn't have one, now Class X crushes anyone besides Y because this additional mobility allows it.
The same goes for cooldowns, because everybody got offensive cd's, everbody also needs defensive cd's because elsewise they get crushed in Arena because they just get stomped by those offensive cd's.
Balancing PvP around the microcosmos that is Arena was a mistake, that only works if you design your entire game around that mode.
Battlegrounds would have been far more suited as core game mode, but that's not going to happen because Rated Battlegrounds are basically seen as weird sidekick mode of PvP, which in itself has been the weird sidekick mode of WoW for a long time by now.
