I am pretty sure people who wouldn't mind going to mop classes either don't remember how much of a shitshow it was or played just 1-2 classes.

Vengeance tank mechanics, people removing you from arenas and deleting your account.
The only thing I miss from mop is being able to cast fillers on the move.
