18 rogue/2 monk shadarkai can't remember who posted the non-assassinate SWF DPS rogue in the rogue forums, but i was thinking an extra multiplier on 19-20 from fire stance may be a little more dps. 41 in vistani for capstone (and melee power and centering and +1 crit multiplier/range etc), 31 in assasin for +1 crit multiplier, 3 in acrobat for speed and 7 in ninja spy for extra sneak damage and -40 threat generation. 18 in shadarkai for all the shadarkai goodies. you "waste" 2 feats for adept and master of forms, but get dodge and precision back (for instance) from monk bonus feats. you have to use cloth instead of light armor, but with evasion the lesser MRR isn't quite as bad. i will make a real build eventually, but just writing this down so i don't forget. i do like assassinate but just wondering if this is another option
