when i was new to this game i would expect monk to be like this http://www.youtube.com/watch?v=ERwVVV96yPA
i give you some simple combo example from this video of another game.

your AA is great and fast.
your passiv skill have a 50% chanse to do a tripple stike wich leads you into some other combos.
your other combos deals more dmg but it drains your mana depends of wich combos you use, its fair play more dmg = more mana drain.
you have skills like a RANGE attack, 1 skill wich deals more dmg if the monster have high DEF. and a veary strong attack wich takes all your mana for 1 stirke, basically a LB.
You have your buffs wich last for like 1 min.
Now this is a little bit of a offtopic but yea...
