My favorite are bad tanks who rushed to 50 on a DPS class yet they can't hold aggro, save goblins or even know where to go in simple dungeons like Brayflox, then when you call them out on it they start a peeing contest about how they've "cleared turn 1-4 of coil" as if that makes up for their laziness, ignorance and lack of skill as a level 34 tank/healer/etc.

The good news is that from all the lazy, poor/low skilled players (mostly tanks) I've seen leveling their alt classes in DF that have "Done Turn 1-4 of coil" on their mains yet can't hold aggro on more than one monster or mark them as tanks, don't DPS as healers, etc. coil must not be very hard.
