This is aimed at hunters in wow but might be useful elsewhere. I haven't tested these, they are just ideas. Mostly pve, but might help a bit in pvp.

0)Have a pet tank.

1)Have the hunter follow someone who is following your main. Only useful if your main keeps aggro, or if a pet does this might give some more leeway. In pvp you'll only be able to shoot if they go for your main, which they probably will if its a healer.

2)Have the hunter as your main, pull the mobs back to your alts on follow, stop their follow and run the hunter forward(away from alts) before turning around. In pvp if you have hunter+cloth, your hunter can shoot if they go for the cloth.

3)Have the hunter pull the mob, run back past your alts while you stop their follow, then have your alts pull the mob off the hunter as he/she is getting out of deadzone range to the alts. I guess this is good for laying a trap on your alts in pvp.

I still don't see hunters being a good choice for boxers, but hopefully these ideas will help make the garbage not smell so bad.
