from my other post:

the good: it looks like its not a cake walk, it has mini CSs while you run through, Might be some trap like elements, its finally end game content.

the bad: re-used zone, re-used mobs, looks like a generic raid (run front to back and kill boss at the end, with included linear tunnels) some articfical 'difficulty' by having an AoE kill everyone in a huge range attack. There is only 2, people will blow through these and be bored quick sadly, all the people who have 50s didnt have much else to do.

People seem happy, but i think they are overly excited for something that pretty standard and there is only so much there. DO NOT over hype yourself for it, your just setting yourself up for a letdown.
