If you have a MW 1-hander lined up, I'd personally go for 15/24 for the mobility in group fights, and for chasing down cowards. 5 Powerstrike is still plenty with a MW weapon, speed bonus, and held attacks. Even more so if you're using a pierce or blunt damage weapon, though cut functions quite well as well.
5 ps, 5 shield, 8 ath, 5 extra points (for IF, more shield, or WM by preference; I'd max IF). I'm doing a variant of this build where at level 30 I'm 17/24 (building for 31) with no IF and it's very fun so far.
