If you're looking to powerlevel your enchanting...

You can do massive AoE pulls in lower instances with all of your toons, the same as we do with a single toon during boosting.

Take the lead/main toon and set the loot to Master Looter.
Choose for this toon to "opt out of loot".
Set the threshold to green items.
Ignore loot on every other toon.
Anything that sparkles on a corpse on this Master Looter is something green or better for them to master loot.
You'll miss all the cloth, but won't have to loot every corpse.
And you won't miss any greens or better.
