Imo, people concentrate too much on aspects of the game which in theory take away from “skill”. The cream rises to the top regardless. Same guilds will always be at the top no matter how much theoretical bad luck they can have. And as seen in the MDI where everyone is equal, mostly the same players are at the top anyways
It doesn’t mean on occassion it’s not frustrating, but the end result is the same, and you keep pretty standard gear and class based rpg elements too. Even pen and paper DnD has restrictions. A lot more than WoW.
