I did 5-hunters back in Vanilla WoW. Got them to 60, and had Ellay rock me in AB a few times with 3 mages.

My experience with it was that it worked up to a point, but really starts to get to be impractical once things start hitting really hard, and once AOE damage starts getting really bad.

But that's my experience from like 3 years ago. A lot has changed in the mean time.

Leveling is a joke, but I think that happens regardless with 5 DPS.

Hunters do have huge bundles of tricks though, so setting it up may be fun or a pain, depending on your view of thing.
