HUNTER SPEC HELP PEASE!!?

I would have to say beast mastery for pve, and marksmanship for pvp because if ur bm for pve your pet takes all the agro and u just shoot monster down. In pvp its easy for ur pet to die because it goes running after people and the kill it, so just go marksmanship for pvp and you can shoot them and do incredible amts of dmg even when pet is dead. =)
