It's seems fairly good so far, but I've got concerns.
-It looks awesome, but I struggle to see enemies, there's a lot going on on screen, and effects and muzzle smoke don't help. Constantly having to re-acquire a target I saw first. Lack of spotting and the spot marker which just obscures your view doesn't help.
-The TTK is OK, but the perceived time to death can be low if you get hit with a one packet death.
-The attrition system is tiring,I wish there was a 'modern classic' mode without it.
-It feels like there are only one or two guns in each class worth using, but that's an early judgement.
-Reasonable number of maps to start off, but the road map is sparse. In 12 months time this will be a big issue.
-If you're not in a squad of like minded players, you're screwed.
-And a round of frontlines I played, the attackers had no bomb, the timer was on 0, and the game just went to infinity (I assume everyone left eventually). This can easily be fixed though.
