So I managed to get in to a PUG of Onyxia last night.
Man was I dissapointed.
Sure she hits pretty hard, and it's in your best interest to bring 3 healers, but the fight hasn't changed at all.
Ok, so they added one additional add that spawns. Woo.
Other than that, it's the usual:
Phase 1: Spank and tank.
Phase 2: Kill things and stay out of DB.
Phase 3: Spank and tank.
And for all of that effort you get 232 loot. Like really? I was expecting more. Oh well, guess I'll just collect my Thunderstrike and move on.
