Have specializations been confirmed for Battlefield 3? That would be incredibly stupid if they were. They were already laughably idiotic in BC2, actually having to chose between using alternate guns for tanks or using smoke when oh, I don't know, in Battlefield 2 I was able to use them all.
Putting health bars back in rather than health regeneration would be nice. Oh right, we're talking about DICE, the people who are going to beat Call of Duty by being Call of Duty.
Edit: Judging by how easy they were able to cave into the Call of Duty trends, my worry is that BF3 will just be an extension of BC2.
