Yeah, 30-9 is a bit excessive, but Power Strike works as intended, I promise. I'm a 27-12 build this gen and use a long weapon, kind of wishing for 1 or 2 more athletics to get some momentum in my thrusts. left swings and overheads are going to deal the most without much velocity, and if you thrust, you're gonna need some speed behind it.
With a 31 / 34pierce weapon and 9 Power Strike, I still need to hit a lot of people 3-4 times, just the way it goes.
