Maybe, but IIRC every one of the top 5 Fox players say that Fox is either even with MK or that Fox beats MK (which has been consistent for at least a year). On the other hand, the opinions of the top 5 Snakes have been mixed on the other side of the spectrum for years now.Well Snake MK isn't close to even either 6/4 at least.
And no fox wasn't included in my statement about asking the mains. There is the same kind of evidence that there is about Snake going even with MK. Snakes have been upsetting MK's for a while. Doesn't change the fact that the MU isn't even.
