I have been reading a bit on the forums while at work today, but I dont agree on all the hate. My first impression:
Ironsight is nice, the zoom is ok, i dont see all the fuzz about it.
Graphics are nice, dont have anything to complain about there. Dont know my FPS, but it feels good enough with everything maxed out on 1920x1200.
Walking feels a bit weird, like im walking on ice, my character doesnt stop when I want him to stop etc, can get used to it I guess.
I wish there was a mode like in CS and CoD where one team plants a bomb and the other team defuses it. The current modes are confusing and theres enemies all over the place, a bit out of control or w/e.
Having to toggle ADS, Crouch, Prone is very annoying but I guess I can get used to that aswell, however I hope this is something they are planning to add in the release.
Overall its fine, I can have fun playing it after getting used to some of the stuff described above.
