i'm rolling 3 BMs and a Holy Priest right now to even out with my lvl 73 BM Hunter i've already had. if you're gonna PvE alot, grab some bears. they have Swipe which can hit everything in front of them and at 38 they can learn ThunderStomp which hits everything around them. 40, you get Volley, which you can later use once you round up a nice mob and mow down alot of things. at 20, keep Aspect of the Viper up when in combat, you may suffer damage loss, but you'll have no downtime between battles cause of the constant mana regen off your ranged hits. just make sure you get atleast one hit on the enemy before your pets take them down. 5x MultiShots work alot to tag a mob. that and Serpent Stings. I'm gonna use my Hunter party strictly for PvP once i cap them out to 80. I might run some Heroic 25s once i get there, but right now I'm just workin on them. As far as glyphs go, grab the Glyph of Mend Pet. You'll use that all the time and you get 20 happiness on your pet per tick or every other tick. Better than rackin up a large grocery tab. Bears will eat just about anything too, they're not picky. Look up Brummly on Earthen Ring Alliance in the Armory if you wanna see my spec.
