I'm on turn 4 coils w/ mnk as my main and the only issue I think you'll find w/ mnk is where you are forced to start combo's over and over in fights like titan where he jumps away (perfect balance comes in handy). But w/ that aside, mnk out performs drg easily in any extended fight. I myself have a relic +1 drg/90 gear and even on dungeons like AK, my mnk destroys bosses faster then my drg and I don't have the +1 yet for mnk nor any ilvl90 gear. Mnk can be a dps monster but it all falls down to combos and using your buffs like blood for blood and internal release. The only change I would like to see would be extending greased lightning duration a little or twin buff a little but if that never happens I won't lose sleep about it.
