I just saw a lot of posts about Ashran and people complaining about stuff including rep grind. I just wanted to throw out if you need rep, the turn-ins from looting dead bodies ie: Orc Tooth, Tauren Hoof, etc. etc. now gives 2750 rep per turn in (human), before it gave 300.
So if you go alongside the raid group, but not in the raid group so you don't have to roll against 39 people, loot faster than other people and you can get revered (needed for all the gear) or exalted pretty stupidlly fast. Or if you are a stealthie you can go gank/loot out of raid group, same thing.
