For your average player on battle and siege, you'll perform better with a str-heavy build. 'Cause with a str build you don't need to be good, you just need to be lucky. Or you just need to roll with a group of people, grab a big axe and overhead. It's not that hard.
The ability to kill others in 1-2 hits and be able to take 10 hits yourself is a pretty big advantage. If any of you remember Wallace, he was a beast back when he actually played. He killed most everyone in 1 hit and it took me about 12 hits to put him down. Not to mention the fact that he chambered most everything you threw at him.
If all you're doing is a series of 1v1's of course higher athletics is an advantage. I don't know how you guys do it over in EU, but in NA we don't take turns fighting each other.
That being said, I personally use more agi than str 'cause I can't stand being slow and str builds are boring as hell.
Anyway, balanced builds are still king in my opinion. Fast enough and strong enough to get the job done.
