I started off as a gladiator and tanked for all the dungeons in the storyline from 15-50, from Sastasha to the Praetorium. I did a relatively good job, almost never losing aggro on any enemy. Not a perfect job, but enough to make the healer's life a little easier, only having to worry about healing me instead of themselves or the rest of the group. After finishing the main story, I decided I wanted to change to pugilist and try out DPS and see all the dungeons from a different view.

I am now a level 36 Monk, and am currently running Brayflox's Longstop and Sunken Temple of Qarn, and the vast majority of those runs ended in failure because the tank can't follow instructions or do their job properly. Now my first assumption when queueing for dungeons as DPS is that we're not going to finish it because the tank can't tank or that they'll do something really stupid, like ask the DPS to offtank for them. Seriously, that's what one tank asked me to do. As a gladiator/paladin, I've never had to ask the DPS to offtank an enemy for me. EVER.
