No, i wasnt playing AoB, if i was - i wouldnt have gotten where i did. Basically shotgunned everything on the way.
Berserker is fine and dandy, but if i get Berserker - i wont have TaN 3, and 4% is looking to me like hanging over chasm on a thin thread.
As for AoB, i believe large med-kits berserk effect is much, much, much shorter than that of berserk pack.
