The major advantage with DW is that you can use a lot of the Touch Attacks, same with SH siince Touch AC is by far lower than normal AC. Easier to hit, especially if you're using Weapon Finesse, everything you can do to beef up your BAB and any Enhancement Bonuses you can get to increase your attack rolls...

Desert Wind's last move, 100 Fire Damage move is useful to 1 hit KO lower level stuff...
