Not certain where to put this but the achievement is from garrison so this seems fitting. Blizzard really needs to stop sending the hat from Charting A Course to every character you log into. It is really frustrating to not be able to delete characters without getting to a mailbox which for DK and DH means doing a few to a bunch of quests. I mean seriously they just added an account wide tab for cosmetic gear.
Just needed to vent a bit because now I have a DH on a server to try out the animations for female nelf and I want to delete her but I can't be bothered to do the starting zone again.
