I noticed that certain classes turned great players into insufferable assholes. For example, a one my players was great when he played a Paladin, but turned into the most powergaming metagaming power tripping faggot when he played Wizard. Sorcerer players have been good at both gameplay and roleplaying, while Wizard players have always been awful for some reason.

Summoner is like Wizard turned up to eleven. Hate that class and anyone who plays it.

Warlock attracts a lot of edgelords and, for some ungodly reasons, sex pests. Usually bard and druid are reserved for that. I can count on both hands the amount of players I've had who played female (tiefling of course) warlocks who were obviously working out some kind of fetish or kink.
