Just started working on Wintersaber rep for my main group. The meat quest still gives 250 rep, but in case you don't know, you only have to do it 6 times. After you get to 1500/3000 Neutral, another quest opens up to kill Winterfall Furbolgs (5 shaman and 5 ursas). It also gives 250 rep. Clearly, this is the preferred option if you're going to do this grind. The only bad part is the travel time back and forth for each turn in. But it will get better next week when they add flying. =)
