Phase4 will not be new by the time TFC comes around. TFC2013 had only 1 week of Rachel & Momiji MU experience.
and everyone used rachel cause she was broken as shit, when marie came out she was balanced and we didn't see that many of her lol
MR was common as fuck in the first week that she was released then people realized just how average she is. There also wasn't a major tournament like TFC within a week of her release.
