NOTE the 15 ranger 1 monk build is NOT limited to a kama they can use the full ranger weapon set and retain the Wis bonus to AC, the wisdome to ac is only lost if you wear armor or use a sheild.
The build that go formor monk levle for centered ac and wind/ocean stance ofr more AC are limited to kamas.
That all being said my Tempest monk (6rgr/10monk) who DID not go for PA (8 str base), but in the perfect situation pally etc, (but fightign not tumbling or useign clicky boosts), should hit 90AC, still hits for 25-35ish +8 guile, +8 thrane goggles, +1 force, +1d4 slicing, +2d6 holy Per kama, I know a S&B fighter will do more base per hit, and definetly have better crit options but that extra 16+1+1d4+2d6 points of damage on the off hand at 10% faster speed all the time has got to add up way FAST and i would not be at all suprised if i was out damageing a S&B fighter, (maby I'll look up the dmage calc and run the numbers then edit them in here) and this guy was build with the aim of AC AC AC SAVES dps, sac a Few points of AC off the top end you might ocational get hit on eliet by harry on less then a 20 and you could add a bunch more dmaage.
***EDIT OMFG....
So i ran the number throught this damage calculator:
http://www.afterlifeguild.org/Thott/ddo/index.php
NOTE: this does NOT add the the 2 extra attacks ddo grants twf now so off hand was onyl getitng 3 attacks per set, I added 10% more swings for tempest so kwaiii's DPS should be higher thsi was don with average buffs verses what we fight 90% of the tiem at high levels namly raid bosses/mobs I weighted in towards the fighter in a lot of ways IE i gave them both GS weapons i assuemd the fighter had a khopesh and all spec feats I made both haflings since i was useing my guy and assumed the AC build S&B some how bought a 18 str still ie 16 starting after the -2 compared to my 8 starting, I gave the fighter a Bloodstone while omitting one for me since i dont use one normaly (dont have a spair for one thing), I'm useign dul Kamas...
The Fighter came out at about 105 DPS Kwaiii Came out at 138 DPS, I am not built for DPS, I'm a build for AC above all else, if a S&B fighter can not even come close to me, (and this was missing 2 of my off hand attacks), they can not come close to ANY twf robe AC/DPS build.
