Yeah I quit WoW in 2009 and never went back, which would have been 15 years ago now, and lines up with what the OP was saying for timeline. I remember all the coming class changes that would homogenize things drastically, and already being rather annoyed with how things already were, I dipped without a regret, other than losing touch with friends from there. I’m only in contact with a few of them at this point and that’s a little sad, but we all move on eventually.
