Occasionally I see your posts on the boards and they just stand out and say "C'mere devs got something useful for you to work on." This is one of those.
I say that because Way of the Thief-Acrobat II grants a bonus that doesn't currently fit in with the rest of its abilities (not saying it isn't already a great enhancement, or that it isn't powerful in its own right.) and using the first tier of its line to sync its bonus up would be useful.
For all the people crying out that a 1 + 1/2 STR damage weapon would be to powerful as a finesse weapon, um.....Dex builds generally don't have the greatest strength scores so they don't get a big a benefit, and if that's not good enough then hell tack this on as a modification to RWoT-A I.
"You treat quarterstaves as a light weapon for the purpose of finessability, to hit, and damage bonuses."
