I said hard, not impossible. I will admit I am not privy to fight club knowledge as to why 2wf is overpowered.
Care to enlighten me?
One reason is the following: 13 levels of rogue add 7d6 sneak attack damage, which gets applied to every attack. With GTWF, 5 mainhand attacks proc 4 additional off-hand attacks (and a few more mainhand procs through doublestrike).
With THF, you only have main hand attacks and doublestrike procs.
However, I don't know how the attack speed compares (even with +15% attack speed from acrobat). See below for some more info on attack speed.
Another thing is base damage. I'm not that deep into monks, but I think it's not hard to surpass the 2.5[1d10] of sireth. Additionally, THF gets 1.5 damage per 2 Str points per attack. Unarmed with GTWF gets 1.8 damage per 2 Str per mainhand attack. (This is not considering doublestrike which has a higher benefit for THF than for TWF.)
Here's some technical details on attack speeds.
Quote:Summary of results:
* Alacrity bonuses add together when they stack
* Fast THF (greataxe, quarterstaff) swings per minute (BAB 20) is 86.50 * (100% + 1.0327 * sum of each boost%)
* TWF swings per minute (BAB 20) is 86.66 * (100% + 1.1965 * sum of each boost%) (note TWF gets about 20% more than THF from each percentage of boost)
* Unarmed (monk) swings per minute (BAB 20) is 93.23 * (100% + 1.2939 * sum of each boost%)
