More like there'll be tons of dark knights that start the game thinking they're dps. Their typical behavior would be rushing in head first without checking who's tank and go through the 4 steps of grief (yes, 4) when party members point out they're tanks.

You queue in df as a paladin after expansion and party members would immediately drop to their knees praising their deities after they see you and start woshiping the ground you walk on.
