You pay real money (through MC) to effectively combine the tier 1 and tier 2 modules (C-BIlls) (which take 2 module slots) into one tier 3 module (which takes only 1 module slot).
Ceteris paribus, this gives a player an advantage of equipping an extra module for real money (through MC), i.e. one now must keep spending real money in order to remain competitive.
Combined with draconian premium time prices/usage policy, where only 30+ days packages are good deals (which effectively causes my premium time to be wasted because I cannot play on some weeks), I am not so sure if I will ever buy MC again. I mean, I love the game and all, but I will not play it if I have to keep bringing them money in order for me to enjoy the game (=stay competitive).
Here is why it is largely irrelevant how effective the advantage of equipping an extra module is:
P2W is a very touchy subject. For an anti-P2W competitive player to keep buying MC, the "objective definition" of P2W is not important. What is important is his/hers subjective definition of P2W. Personally, I gladly bought about $80-105 worth of MC so far, but now that I feel that developers' definition of P2W is getting more and more relaxed almost every month, I am not so eager to put my money into the game. For me, and I am sure for some other players too, it is not so important how much "direct" advantage can be bought with MC, but that it can be bought at all. There is a good reason why I stopped playing WoT after like 3 days. I consider P2W model to be degrading to the player.
If a F2P scheme where people pay for premium time, paint, and extra mechbays is not enough to support the game, then I'm sorry MWO–I won't be buying any MC. I'll give it a spin for a couple of months to see if the F2P/P2W balance is going to shift again, though.
