OP sums this up perfectly. I started out as a tank but then rekindled my love for pug/monk and it fustrates me if the tank doesnt go beyond the mob's initial placement to turn them around as most of my skills depend of being behind the mob, but I dont want to be the one to have my back to the upcoming enemies y'know? :P
as a tank i always used tomahawk, then defense buff while waiting for the mobs to gather round me, then overpower to attract the attention of all connected mobs onto me for maybe two turns (or more if healer needs to cast alot therefore counter act that hate)

oh- and imprtance of keeping gear up-to-date and applying VIT stats >.> had a tank in one dungeon with LESS HP than my pug. laughable!
