So, I read that the designer of Improved Two-Weapon Feint intended for Two-Weapon Feint to be a prerequisite, but until you get iterative attacks at level 8 Improved Feint is strictly better than Two-Weapon Feint (Either a full attack with a feint and one attack at -2, or a move for a feint and then an attack with no penalty). In the interest of being effective until level 8, what do you guys think about taking Improved Feint at a lower level, then taking Two-Weapon Feint at level 7 and Greater Feint at level 8 using Combat Trick?
This gives the benefit of Improved Two-Weapon Feint, plus gives more group synergy since the feint applies to their attacks as well for that round. It costs one feat more but it's also more effective at lower levels. The only other downside is having to take a feat at level 7 that isn't useful until the next level.
one changes the action used to feint, the other changes what happens when you actually successfully feint, i don't see why they wouldn't work together.
