Nope, and it would stop me playing COD at all. I don't think the game is all that great, and giving paying players an advantage would just stop me even giving it a try. Paying for advantages in a game like that is no different from wall-hacking or aim-botting, they all just give you an unfair advantage that other players can't (or won't) obtain, so why would I support that?
More importantly, why should the developer support that? It's only going to damage the game, I really wish these companies would be a little less greedy, but it isn't going to happen.
