So, just got done doing it on both Heroic and regular difficulty on my server (Dalvengyr) before the damn server crashed and, I can honestly say, it was fun. We started on Heroic and tehn did regular (a decision that prolly should have been reversed, in hindsight). The only wipe was from the transition from phases one to two on the first boss(s, since there's 3 lol). And, for going in with very little knowledge of what to expect, I can honestly say that it was a blast.
Anyone else done this instance successfully and have anything amusing/interesting happen? Like, in my group, the boomkin druid won literally 6 greed rolls over two runs.
