Me personally I was really disappointed to hear that they have Normal and Expert. Having 2 version of the same boss really kills the lore and immersion for me, it just doesn't make sense. I would have liked raids to be more persistent in their logic. Having 2 versions makes it feel like the world is catering to the gamer, trying to make it easy for them, whereas just 1 raid its like 'this is what it is, either you can beat me or you can't'. I really liked that authenticity that one raid brings. Edit: Scooter has clarified that there are 2 modes for dungeons only, not raids.
