Right now I find Kitana much more difficult than Mileena, because Kitana is harder to keep in the corner, and her d+1 is a little harder to beat. Mileena's d+4 is easily beaten, and she gets destroyed in the corner (at least in my experience).
People claim these match-ups are only 4-6 for Sub anyway, so are people really having that many issues? Or are the match-up charts wrong?
Also, I think Sub's dmg is just fine. He gets 38% from a JIP. He only gets around 25% from a naked freeze, sure, but then that's more than Noob gets mid-screen. You can claim that Noob gets his main dmg from projectiles, but he gets less than 25% for each, and his corner pressure isn't as good as Sub's. To be honest, Sub shouldn't be getting naked freezes from across the stage anyway. Once or twice, sure, to make the opp think twice before throwing out projectiles, but he should be making his way to them and pushing them to the corner.
Besides, you only have to freeze the opp 4 times to win a round (not counting breakers). That doesn't seem unreasonable to me.
