Try this.

3x mages, grouped together.
Two on follow, lead with the third.
Equip +stamina gear, that's all you care about.

1x Shammy (two would better), also on follow behind the lead mage.

Run around, gathering as many non-aggro mobs (ideally 3 levels above the mages, for maximum experience) as possible.
Use arcane explosion.
Once they're tagged, have the shammy drop a magma totem and a stoneclaw totem.
The second shammy, if you had one, would do the same, except stoneclaw would be round-robin and not both at once.

Rinse and repeat.

As long as the mages are in a group (minimum 2 toons)...
And tag the mobs first.
And only pets do damage outside of their group (totems and damage shields are pets).
They get full experience.

It is a way to AoE boost toons.
