I’m raid leader for a 12/12M guild if my mages decided to play Arcane or rogues went Sub they’d be benched.
There is no “different builds” at end game. You pick the optimal build to clear the content the easiest.
The reason people are freaking out about the swap is because they want to be optimal. Not because they want different builds. They want the build that offers them the easiest solution to their problem at hand.
Blizzard is taking everyone to the ice cream store and telling them to pick one flavor. Folks are freaking out because two minutes into eating Vanilla they may want Chocolate.
Wait and see how hard it is to swap covenants and for them to showcase the full system. I do not believe they have done so yet. They said you can swap, so you can swap.
If it takes twelve hours to swap, well they gave you the option to do it and if you want to be optimal do it.
Top raiders in Classic played 12+ hours a day to get the best gear in the game to be optimal.
Wait and see what their solution is. Ion already said they heard about the complaints with the system. They said if they can’t fix it they’ll toss it.
