I have 2 Barbarians that I put a lot of work into and they were nerfed into oblivion and basically useless now. Look at the newer end-game tier lists and you won’t see barbarian builds in anything above a C. The complete devastation of earned gear and builds is THE #1 reason that will push me away from the game. I put my valuable time into the game and I expect to have something to show for it. If I want a seasonal game, I’ll go play PoE or other.
Intentionally selling overpowered new classes into the game, knowing you’ll nerf it later when the fervor dies down in 3=6 months, is a customer-killing strategy for many folks.
I’m going to finish one seasonal character just to get the full experience of the expansion and then decide if I’ll spend any more time and money on the game.
