I don't mind a group that wants to go fast. As a Prot warrior I want to keep the downtime between pulls to a minimum so I don't walk into the next pack rage-starved. But there's a pretty bug difference between a "Hey, I'm geared enough to handle big fast pulls if you want" healer and a "gogogogoffsgoalreadywhatareuw8ing4noob" healer. One makes me happy, the other one drives me into a blind fury.

Exactly this. When I'm tanking, and the healer can keep me up and wants me to pull faster, i'm happy to. Dps, i'm sorry, but i don't care about your opinions on the matter, because you're not tasked with trying to keep people alive. You're tasked with trying to kill things as fast as possible, of course you want to go faster! :)

A question for people - or the queue.
Does the type of tank effect how lightly they are to be 'gogogogo' guys?
I have a pally tank - and on him i tend to be slower as I have to wait for mana sometimes etc. My friend has a warrior tank - who pulls just as fast as he can do so without complaints from his healer. Another alt I have is a DK tank, who just seems to be able to wade in, who is faster than my better geared pally. Finally druids seem also to be quite fast (esp when very OP and go tanking in kitty form!) but they are the class I know the least.

Does this seem to follow with other people experiences?

Cheers
