I haven't had a chance to try the Arms 2.0 spec in raid yet due to well... papier mâché servers.
So I tested out on dummies with no raid buff apart from the warrior's own (Battle shout, Sunder, Blood Frenzy)
On the level 80 dummy, Recount had me at around 1400-1500 dps.
Is that standard ?
I have full epic PVE gear (armory link http://eu.wowarmory.com/character-sh...ar&n=Kilorglin)
I also tried on the boss (skull) dummy. But I had odd numbers there, with white attacks doing less than 100 damage and 700 dps-ish overall.
