Now comparing a pure monk with a moncher:
-both can take gtwf line, power attack, ic:bludg, vorpal strikes, improved martial arts
-pure monk has up to 10d6 base fists damage, my moncher has 7d6(i know both can be pushed a lil more), that is 3d6 or 10.5 difference in damage
-moncher has rams might +3 damage/hit so the difference is 7.5
-favored enemy damage is up to +9 damage
So I would say, in most of the cases a pure monk has better melee dps but not vs favored enemies.
On the other hand a pure monk has better TOD dc while a moncher has free haste boost from fighter and +1str avaiable.
I would not say monchers are behind, but if they are they still close enough for melee to matters.
I see that everyone around is dropping the gtwf line, stunning fists, vorpal strikes and improved martial arts to get cleave, gc and OC. Well in this case I can say yeah moncher are far behind a pure monk in melee! But since I hit for 120 on a stunned mob and crit for 400-500 with a 9%DS and touch of death I'll keep my moncher as it is : P
