Yes, remove WAs (and since we're at it, Boss Mods as well) and go back to the glorious times of raid encounters having 2 mechanics because any more than that would become quite literally impossible to coordinate between 20 players.
I much rather have insanely retarded and stupid shit like Archimonde that melts your brain even with fucking WAs and whatever other addons than having the pinnacle of encounter design be shit like Artificer where you have like 3 abilities randomly overlapping with each other from time to time... and nothing else.
