Well, since the majority of the final fight with Deathwing is on the PTR (or one could assume) how do you feel about the fight?
Personally, after watching it and learning the mechanics a bit, I am greatly underwhelmed. I mean really, unless there is a shit-ton more work to do on it (which I doubt), besides number tuning, it is completely lame and I cannot wait for it to be the end of Cataclysm. Honestly, even the spine of Deathwing encounter seems like a letdown. Maybe it is just something you have to experience for it to feel epic, and I'll try to go in there with open mind, but I'm disappointed as of right now.
In all seriousness, these lame encounters with Deathwing sum up this whole expansion for me and if they are as bad as they seem, I simply cannot wait to judo chop some pandas in the face.
edit: Now that 4.3 has been out, and a lot of serious raiders have seen him by now, what are you thoughts after SEEING it?
