Intimidating Calculation Involving MU's:
This whole "style" thing is going to totally change how to approach a matchup chart in general. If you want to find that "best of 10" thing, it will have to be 3 sets of 10 against each character to find out how just one style alone fares against them, so 9 sets total if you want to fight all three of their styles with each of your styles for a given character. Then combine that factor with a currently silhouetted cast of 24 characters (assuming every single one has three styles.) So just subtracting 3 sets off for your own character (one for each mirror match), that's going to be 24x9-3=213 sets, making for 2130 games played to completely pick apart just
one character and their three styles. Does that not sound horrifyingly complicated yet somehow awesome at the same time? Like, what if someone went through and played all of those match ups, and then some random dude found some tech that totally changed everything and all of them had to go back and be recalculated.
True Mirror Matches?
This is all just assuming we Sub Zero fans want to dissect him down to the very core and want to know which style to use against each character/whatever style they are using, mirrors included. If every Sub player who runs into each other plays differently, there's could be counterpicking mirrors. Say one Sub plays Ice Weapons and loses to a Sub Clone, and hypothetically Sub Parry beats Sub Clone or something.
Playstyles vs. Characters:
Another thing I thought about is the potential for one who is exceptionally offensive as a player say PL or whomever to just pick the offense based playstyles of different characters (say one is a better counter zoner while another fares better against grappling characters or something, I don't know.). Or zoners like M2Dave pick zoning styles of multiple characters et cetera. You get where I'm going. I bet we'll be seeing some really interesting developments involving character loyalty vs. individual playstyles at the later stages of higher level play. (assuming we make it far enough to see it happen. XD)
Conclusion:
This has got me on both ends of the spectrum. A part of me wants each style to be similar enough that it won't significantly impact a mu, making for an easier time grinding and collecting data. But another feels that it could be highly interesting if there was a dramatic change in playstyle by just switching a couple of normals and specials to the point that such pondering is required. If done correctly, it could eliminate standard tier lists and create an odd mix match like "SubZero Clone is top 5, but SubZero Ice Weapons is bottom 5".
