I dont get why people are griping. Unless it changes its tune, it will be as it says on the box - and its bad form to add drastically different gameplay elements to a sequel. Dont blame the company, blame the generation of FPS we are in. Ironsights, medics, prone etc are kinda where we are currently. All the other things, stabilization, adjustable sniper scope etc are specific to realism games. Battlefield has always been a mainstream title. More realistic than COD 4 and its ilk, sure. But only just.
That said, I think there would have been room for some features such as picking up other weapons to replace a weapon of equal weight, making heavy infantry slower moving, tanks with insides and animated internal actions, and even gun jamming and some dud grenades and shells.
Would also love to see an advanced communication rose to support suppression/ flanking, hand signaling and perhaps whisper vs shout vs radio over, maybe even amputations.
All within allowable range. Generally though, its bad form to change things too much. Bad for the following.
Sure wish its the same characters from bad company in this one. Would make sense considering it being a little beyond modern warfare.
