I disagree, when i was in a high end PVE guild, i could spend hours with a training dummy and a damage meter addon, just to determine the best rotation for PVE Arms, and to decide which triket would be better for certain bosses.
And i'm talking about a stance dance cataclysm arms warrior with casttime slam and extra rend ticks, which was way too underrepresended due the complexity of it's rotation.
Of course when i shared my stuff on the ElitistJerks i got banned from an admin who surprisesurprise was anoter PVE Arms warrior.
I think i still have my old spread sheet somewhere:
