At most, this guide is truly if you're a bored healer or tank for the instant queues (on my server atleast). You really only have a week or so to do this, so if you have down time, and love tanking or healing, here ya go!
Basically on release date of 4.0.1 ALL badges below Emblems of Triumph and above Heroic Emblems, will be worth 5gold 50silver. So for the next week farm up as many heroics as you'd like, and break down the badges RIGHT before the patch release for some extra free gold.
Yes, you can break them down for gems right now and get some gold for that, but according to my server the cheap gems are only going for 50g per gem:
1 Dreadstone = 50g = Usage of 50 Emblems of Triumph
versus
50 emblems of Valor = 55gold
I love healing, and it's REALLY semi-afk easy (put in a good movie or some new episodes of Metalocalypse), if you have a good tank friend. I'm already up to 330 emblems in 3 days.
