Firstly, Titanfall could never compete with CoD. There are no indications of that. Secondly, from what I've seen, You have to kill or obtain some sort of score to build your specialist bar. Yes, CoD is dying. It's dying because it's lost their originality. Nothing has been ripped off, because if we play the "who ripped off whom" we can very well go back to the very first FPS games and say that everyone else ripped off the very first FPS game.
