different opinions = different outcomes
cleave does have higher dps if your trying to go for many at once, but appears you always do(showing that you go for 4 mobs and not just one)
i find having groups for many mobs work out pretty excellent rather than soloing most content and being bored out of your mind using cleave and then great cleave. Your a dark mnk i suppose because you ike high sneak damage and that special dark path move(TOd). i see often as a light monk, i rapidly spam ki attacks, and i never go out, i find this is the best benefit to being a light monk.
But it appears for your entertainment, you spam cleave when on cool-down for touch of death.
Just remember when you play a light monk, you will never find a wanting time to switch back, its hard to miss out of the entertaining buffs it can generate.
