I've just started the 2nd level, and first impressions through the first level were "damn, this sucks".
Grunts look like something out of a comic strip.
Elite AI seems to be on par with CE...."hey look at me, I'll take 4 BR volleys to the head, THEN decide to side-step away."
Legendary is extremely easy, but maybe it gets harder as you go on.
Pistol sounds terrible, kind of like the tin-man from Oz is shooting it.
Frags seem weak as hell.
Music on the first level is just so much worse than previous campaigns.
After all this time in development, and this is the best they can come up with? Really?
