I'm curious as to why you'd think Jade gives Mileena problems. Raiden I could see a he's just cheap in general. But I don't see how Cyrax...and especially Jade of all characters can give Mileena a hard time.
Cyrax I'm not 100% sold on yet, but he just has amazing tools. Net beats all of Mileena's wakeup options if she's any closer than long range. He outdamages her by far (he gets over 50% with one bar, she needs 3 bars to get at max 49%). His in-close game offense is on par with hers, even though he doesn't have a low/overhead mixup that leads into combos. Honestly, there isn't too much else. He just has better options. She has to take more risks than he does to establish momentum in the match. Both characters need to make good reads, but Cyrax doesn't need to make as many correct guesses as Mileena does. I'd put it as a 6/4 for Cyrax unless someone can explain why Mileena shouldn't really have any trouble with him.
Jade has her glow for anti-zoning which makes Mileena's long range game risky. It also hurts her ability to build meter quickly since she can't chuck sais at will. Mileena can't get too crazy about getting in on her either because her U+3 and B+2 are good to keep Mileena at a range where she's gotta wait for a mistake. Both of these moves are safe against Mileena, and force her to either 1. try to close in on block, 2. throw out a telekick in anticipation of another attack, or 3. just be patient. Then when she does get inside, Jade's EX glow prevents Mileena from rushing down too heavily if she has the meter for it. Jade's B+2 also punishes both roll/ex roll and telekick with ease, regardless of air sai followup, for combo damage.
Mileena can't really force a lot of frame traps like most rushdown heavy characters can, so her best range seems to be at the range of her infamous D+4. This would be fine, but since Jade's normals at that range are a bit more rewarding (U+3, B+2, F+2), it's still not much in her favor. Mileena does have better offense in close than Jade does, and her low pokes will pass right under her shadow kick. But at Mileena's preferred range she will be mostly relying on those low pokes to try and get in for damage or bait a mistake. While Mileena's pokes are great, she can't really win the match with those alone.
I'd say it's a 6/4 for Jade. As long as Jade doesn't try to get too aggressive at the wrong times, then Mileena has to play by her rules for most of the time. When Mileena does gain momentum, Jade's only escape is EX glow, but that's still enough to respect the option. I'd like to hear why you and THTB think Jade
doesn't cause problems for her.
