Stop lying.
If i said that you(and all wow players) can’t change your mog in wow anymore for any existing character and new characters have just 1 mog change to make, you know what would happen?
Mass quitting.
Mogs are a reward, rewards are what the vast majority of humans derive pleasure from, you being satisfied with watching paint is your solo problem.
But you are in fact lying when you say that rewards do not matter to you.
1 hit from the Heart of Azeroth healing power is enough to fully heal it.
