I would like to see Studied Combat thing turn into:
--Get Int bonus to hit and damage for Int bonus rounds (Insight)
--Start as move action
--No 24hr limit, but only can study 3+Int Mod number of times a day
--Free action take a number of rounds off when you hit. Do a extra d6 with reach round ended early (precision like sneak attack);
Example: A 18 int character could use it, after you hit, you decide to drop 2 turns (leaving 2 turns left) and get +2d6.
Have talents to make
it swift
let you use inspiration to study
do at 30ft range
keeps combat join for them, limits it some, and keeps in spirit of class.
