Well after finishing campaign mode, my summary of the game so far is that it's rushed. The campaign is very short, shorter then BF3, BFBC2 and the COD games.
The maps are small and not as fun as the others have been, not to say they didn't have their moments, the weather effects and the storm was awesome and the driving section was fun for a short time. I think the weapon balance isn't as good as it should be, the PKM LMG can't hit anything even with bipod down even while holding your breath, the scope just jumps all over the place.
That AA tank can't hit anything to save it's own life, feel retarded shooting some infantry at point blank range and the soldier is like, look at all the cares I give.
Some of the AI scripting in the game isn't as good at it should be for example, the three jets that are taking off in the hanger can't be destroyed at all even with direct hits. The section where you are on the Carrier and about to enter it, the outside map changes so quickly that all the "war" outside just stops and the ships textures turn off to a more dumb mode, felt that was pretty poor.
I did enjoy the campaign for the story and hope to see where the story takes us next year with Battlefield 5. But for now, onwards to MP!
