I guess u'r talkin about a 2h PVE dps spec, since the priority here are the boss fights and single target dps there is no explanation on why are you using improved charge/anger management while not bein able to click anything but HS/cleave, if u'r not using either MS nor slam you have a very boring experience ahead of ya
. ( In my opinion there is no leverage why not just go full fury than this hybrid spec just to be able to use 2h.
Anyhow, back on the subject.
I've raided 80% of my raid time as 31/5/15 which is dps/OT. At the start of MC it was crappy as hell, i for one suggest goin fury at start fo sure. Later on if u get your grab on Bonereaver for instance go Arms. OT are very much needed in general so 31/5/15 is gettin quite enuf dps contribution to be in top half of the dps while bein able to quality OT. Must mention that i was horde so WF is the love of the arms warrs. With it i was often in top 5 on the fights that allow it.
All in all, use the fact that you are an OT and not required to do top notch dps as pure dps classes. Most of the progressions are made by controlling the fight and not by draining your mana out.
