I think you just need to ensure you got enough power strike to actually make a mark on the platers, I went 12/27 awlpiker for a generation and it did splendid, only problem i had to deal with was ranged. Otherwise you end up being glancecity mayor and find you can't find certain foes, even though this is good for anti-archery being able to catch ranged.
Not sure how'd you be able to do much damage with an 11 athletics build, 9ath worked good for me being able to go in and strike then quickly flip away before they could engage in heavy melee combat.
This is what I seen when I played agility piker which is a lot of fun and a interesting playstyle itself.
I am just not sure how you would manage to get good hits on people with 2 powerstrike, even at I beleive 4powerstrike I had to becareful with my stabs otherwise I'd end up glanceing.
Ultimate build in my mind 12/27 for smaller battles and duels like on community, but on NA_1 you have to be extra careful since often you will find yourself always being shot at by archers and will get blackbarred or killed before getting to the melee.
You really have to use a weapon with pierce damage with low powerstrike, a spear or pike is the best choice.
Another thing I enjoyed is that you could backpeddle a whole team and skip around all the heavy STR builds and tag archers and unsuspecting people in duels.
Strength builds to me are really slow and tasking and I can't play any other way besides agility crutching it.
Now I am proably gonna attempt a one handed swashbuckler or bump up the strength and get a good ol'pike.
Also you will make a lot of fucking money with an agility build like this and so forth, thus a +3 weapon is seeming worthwhile as you can recover money loss and pretty much make gold regardless of the multiplyer.
