i will be blunt, i don't think monk need a front combo... but one combo without positional recquirement.
i'm almost amazed as no one did notice that the monk feel more like a rogue and the actual rogue feel like a monk.

the monk don't need to have position he will simply crush the enemy with him power, he don't look for tactics or stuff like this. so far at my eyes, the monk is not a monk, but more a true assassin or rogue class that will fight the enemy from side and back... when the monk must be focus on more complexe combo without relaying on the position. but well...
