I drank the kool-aid and went all in, premium. I was on the fence until I watched one of the teasers that ended with spotting a pink box, and hearing "spotted, delicious donuts!"
I've played it about four evenings in a row. It is fun. I like the feel of the weapons, the sound is very good and I think it looks good. I die real quick, but if I get kill (rarely), that's pretty quick too.
It feels like BF4 (and BF3) are meant for the COD run and gunners, and this feels even more so. If I stop and look around for second or two, I'm either getting sniped or beaten to death. (I am a BC andBC2 fanboy, and I'm not ashamed to admit it).
So I'll probably play it a while longer, but BF4 is calling me back.
