Indeed it was fine. You got 4 for 1 damage output out of Leap Attack, took the penalty to AC with Shock Trooper and got a x3 multiplier the turn after you charged [if the victim... I mean target... survived] with Combat Brute.Listen here sonny-boy, back in my day we had to choose how much bonus to give up, and WE LIKED IT!
We also never got a 3 for 1 damage output and THAT WAS FINE!
Iirc leap attack was errata'd to only add a multiplier for 3x damage.
It was when you threw in Favored Power Attack that you got 4x.
