You know the ones you acquired having your alts log in and answer those daily trivia questions to level up via brain power?
Yeah those.
Go spend them.
The Dalaran vendor has trinkets for sale. Trinkets that are level 320 if you’re level 120. Good for getting fresh 120 alts up to minimum level to queue for a Warfront or two. And they’re cheap. They also sell 320 chest, boots, gloves and rings.
You got 200 of those badges for free simply by logging in during the anniversary event. More than enough to get all of the 320 gear pieces that the vendor sells for your class.
Vendor also sell rep tokens. Rep tokens that are Account bound, not BoP. Buy a bunch of the ones you need, mail them to the needy character and get that red dragon unlocked from Wyrmrest Accord.
So head out to Northrend, and hit up Auzin. He’s a blood elf but don’t hold that against him.
