I might just have to pick this up and start playing again. Tried it out for a week or so, didn't like the guns in it, but love the intense action of MP- however, I really like BF4 better, all around better mechanics and physics, plus the gameplay is more my style (tactics vs arcade style that COD has down pat).
I wasn't too sure about it at first (still not 100%) but it does fix a lot of the issues Blops2 had. If you do get it again let me know.
