Don't play pathfinder. Can't even say it's worth raiding for ideas. My Player Group's power gamer keeps muttering from time to time about how we should play the game and that she wants to play a wizard again.
That alone is enough to make me want to kill it with fire.
That said, I have read the rules and I have this to say about monks, having one min/maxed monk and one player playing a much more poorly designed monk trying to play catch up while avoiding "cheese".
Monks, straight up, suck.
If you allow a player to dig deep. Dredge up 3.0 stuff. Check out every obscure book possible. Custom build some magic items, they can be whirling dervishes of doom, even without TWF or THF or even Greater mighty wallop.
But from the point of view of watching the difference between a Min/Maxer/professional-accountant-who-stares-down-the ATF and a "normal" Player who wants to play a "normal" monk is startling. I will use his PCs name, Kolos is actually less effective then the In-It-For-The-LOLZ Archer. The Archer at least gets to hit the BBEG from time to time. I've seen combats where Kolos won inititive to the bag guys, but lost to his own party, and NEVER GETS IN A SINGLE SHOT. More then once. One paper, he's an effective PC, but in the game, he can't beat out the comedian. You can blame it on a meandering PC concept and multiple rewrites, but the multiple rewrites are because he can't seem to get things to work, and is too damn prideful to let anyone "make his character for him". At times I wish he went back to playing a dwarven cleric. He was boring as fuck, but at least he didn't mope.
I see a great deal of theoretical work posted on this thread, which is well and good, but I actually see what happens in 3.5 to monks under the base system. You have to WORK to make monks awesome. If in 3.P, monks are nerfed, heaven help them, because the dice sure won't.
