How not to be a mentor

[Kohashi]

A skill issue you may have no control over, such as the quality of your tank. And DPS I suppose, if they are very slow and don't burst things down quickly.

I highly doubt that was the case otherwise the entire discussion wouldn't exist. I usually play DPS and healer in expert dungeons and while I do heal, it's not like I stay there spamming it. There are very rare occasions when there is an inexperienced or badly geared tank that requires babysitting.

EDIT: Never mind... I just saw they did 0 damage. I don't think I ever saw anyone doing 0 dps, not even a damn dot. The audacity to play the victim.
