I've never been outdone in raids or instances by an arms warrior but most of the time in PvP, me v arms, if they're geared he'll usually pop a MS crit ,Execute crit at the same time i have him in execute range and beat me. But thats about it. I've crit larger as fury than as arms as well. 7k execute as fury, 5k as arms. and as fury my AP is 2160+ unbuffed and last time i went all out buffs and all, because of fury buffs such as rampage, and imp. zerker stance i hit 4300+ AP. thats including totems, the whole nine yards
