I love my hunter, just about to ding 70 for the very fist time (about 600k to go) I'm seriously considering running a pair, now I know the game so that fast levelling should be good. One would spec BM and go with fast shots, mainly auto shot. One will go MM and go with a high damage pet. If it goes pear shaped both will be able to FD. As long as the pets are the same level to you they have no issues at all tanking anything up to an even level elite. Bosses are too hard, with the extra abilities, especially immunity to stun.

But to have two gorilla's or a gorilla and an owl (thunder stomp and screech) you'd be able to mow down large mobs in record time. In fact as a lvl69 my only difficulty is more than four or five adds.

To be really effective, adding a mage to the mix with an AoE immobilize...

Sure three mages or a priest and two mages would be more effective in 90% of cases, would kill faster and work better overall... but thats the route most people go, having two hunters and a ???? would be different and interesting.

((IMO))
