I have an idea. Say your main is a fully epiced heroic runner and earns badges every time your on. But also, your greened 70 character wants some badge gear too! Well, heres the plan.
First, on the badge runner, buy some stuff you can sell with badges and send them over to your greened char. Say an item requires two nether vortexes that would look great with your character. Monsoon belt (Monsoon Belt - Thottbot: World of Warcraft) requires two vortexes. Contact a GM for a trade back. Once a GM receives your ticket and talks to you, say you wanted Monsoon Belt (or w/e) before but you now realize it sucks (don't spend the vortexes!), and want to trade back the nether vortexes for the 30 badges you spent on them. Say that I find no use with these vortexes now and have enough money or w/e, just be convincing.
Now, there are many thing where if you put them on auction house, or mail them to another char they'll still be with you. idk if this is true, but after you log off you should have the 30 badges on the greened (can't do heroic) char.
EDIT: As I said in a later post, DO NOT spend the vortexes on the monsoon belt, say you found an upgrade or your going to run something for a better drop.
