at 26? Yeah, MAmmoths are probably your best bet. GREAT cash too. At 30, with Fulfils (an origional spell) and charm, you can even swarm the orcs if you so wish, or theres various other swarming posibilities in various other zones.
Outside paw might be an option if you're fairly decently equipped. Going to have to fear kite them thuogh. I believe the aviak roost is probably a bit low for you, but might be an option.
Lets see, oldworld zones...Umm, Upper guk MIGHT provide a little bit, and at 27 the option of "semi swarm" kiting opens up to you. Send a mob after a much stronger one, (blue vs. Yellow, preferrably), let them fight til one's almost dead, invis to break, snare, fear, and melee down the charmed pet, then get another victim for your stronger guy.
Slower than normal swarming, but with our DD song nerfed and mleee abilities, quite frankly, being crap, this is a half-decent tactic if you can pull it off until 30 when you can actually swarm.
