I support this, as a career tank myself. Its hard going as a smn or something in a 30 something dungeon and trying to 'teach' a tank while not coming off as naggy control freak.
EDIT: Although... tanking, I've noticed many dps and healers like to cast something just as I go to pull. That is a no no if you don't want something gnawing your face off while I run around panicking spaming flash, provoke and overwhelm, trying to regroup the enemies around me. ^^;;
