2 AP - 1 STR, 1350 AP = 675 STR there son, and we're not factoring in the 50% AP addition from berserk. So let's say you're another fail VIT tank with the standard fare 300 STR:

300 STR = 600AP * 1.5 Berserk = 900- again taking no other stat modifying ability into play.

If you want to doubt me, fine. If you want to call me an idiot, fine. But don't you *dare* use bullshit math to incorrectly prove your point and call me a liar while pulling numbers from out of your ass. 1200 AP is easy for a warrior, and if you're struggling it's not because the math is wrong it's because the way you're building your warrior is.
