I respecced back this morning. :)
Currently 0/20/39; very nearly at 70 now. My crit is at 21%, but I'm a little too overbalanced in favour of Agility currently; I need to work on my ap some.
BM is a spec with a lot of great things about it. However, I had previously tried pure Marks, twice...now I've tried BM...and I can honestly say that I'm never going to move from Survival again. As a Hunter in this game, it's who I am, it's who I've always been, and it's who I always will be.
