Shoveltusk Herd + seed of corruption = fun
Fly to Howling Fjord. Find Shoveltusk Herds. Start seeding the ones furthest away from you. Seed them all. When they all group up on you and start hitting you, use ShadowFlame (yeah, it has a use). To trigger all the seeds. Collect your Shoveltusk Flanks.
In about an hour I collected 68 Shoveltusk Flanks. Nom Nom Nom.
For even better results.. let a guildie skinner know you’re going hunting and allow them to follow you around and pick the money up off the ground.
