Warlocks, you want Green Fire?? Check out this..
It's a non-supported, could-get-you-banned, cosmetic only, so only you see it patch. The cool thing, is it give you GREEN FIRE. Aphroditi has figured out how to turn your fire green in-game and on most of your key icons. I don't think I am going to apply this patch, simply as I've recently gone back to Affliction and immolate isn't even on the top-10 keys any longer.
