I’m not a big achievement guy, but there are a couple in the game that really speak to me, and this was one of them. I started planning for this a year ago back when patch 3.0 was on the PTR.
By the way the clothing required for the Disturbing the Peace achievement functions the same way as badge gear, meaning once you buy it there is a a one hour period in which you can sell it back for a full refund.
As far as getting the Violet Protodrake goes, like I said, I’m not a big achievement guy. Maybe next year 😉
