Just another hunter chiming in for the person seeking advice. To cut this short @Blackdamain, is absolutely correct with his stat priority suggestion as well as what follows for rotation. I will add to that with the fact SKILL also plays big part as well as managing your macro’s for pets and other situations that arise during M+.
As far as @Stryper and his alleged 7k dps mite just need to be educated on his “Details” addon or w/e he is using. From the start of the M+ dungeon you set Damage>DPS>Current, at the end of the dungeon you wanna look at Total Damage done OVERALL which is gonna be your TRUE DPS the whole dungeon.
The 7K you pulled on Boss or trash with buffs up sure not included pots, or flask is irrelevant to the actual damage per second that you do that is purely for that segment my friend and as others have stated 7k for MB hunters at this moment is very rare in deed.
