Oh, plenty! I get way too worked up at times. Primarily, though, it'd be people pulling enmity when tanking, and then running AWAY from me, rather than coming to me so I can more easily grab the adds. Never understood why people run away from the tank when they pull for any reason.

Tanks taking too long to pull, meaning dps build ups (e.g. aetherflow stacks), or pre-cast shields etc., fall off. Hate that.
