I agree totally. I've noticed I can only spend a long duration on the game when I am playing with some friends, alone, I play a few rounds and need to take a break. I definitely hoped I would have been playing it a lot more but I'm not.
If I'm honest, the current map's suck ass for the most part. Visually, they look awesome but I prefer the larger maps, which they have completely strayed from. Even bringing back Operation Firestorm they have shrunk, which sucks. They seem to be focusing on this "Get to the fight faster" thing which is not what Battlefield is about.
Overall enjoy it, just hope they start releasing larger maps! Redsec is pretty fun too but yeah nothing crazy
