Also, concerning pve, the primary problem lies in the reduced and mixed together class roles and the fact that everyone has potions to mash. In other cases/games where class division means something, even max-geared dps get down'd like flies in seconds at the highest difficulty maps. And the second most important, tanks are actually capable of monopolizing the aggro and incoming damage - yes, it does require timing and practice but it's there, it's possible.

Here in AL --due to game design-- there's neither content elite enough to make a tank necessary nor an appropriate skillset for them to effectively tank anyway. At this point of the game, it's too late for drastic changes IMO. Dps is the optimal path for elite farming, no way around that.
