1) Shorter queues do not make you a special snowflake.

2) Save the tankserious crap for higher level stuff and raids. Go into lowbie dungeons and pugs with the expectation that you will be herding cats. If you're stuck with a party member who keeps pulling off you, don't call them a f*cking idiot, prove you're the better player by following their target and taking threat back.

3) Really good tanks thrive on recovering from and dealing with less than optimal pulls and scenarios. If you can't deal with a group that doesn't perform flawlessly, you shouldn't tank for anyone but your trusted friends and guildies.
