i disgree with 5-5 for sheeva purly for the fact that all sheeva has going for this match-up is her in close armor moves, roll out and gunshot is sheeva's pain in the ass due to the fact both can punish fireballs on reaction, roll out can evade tele stomp and in some cases when EN (its rare to happen) can cancel her armored grabs. i'd say 6-4 in strykers favor
That's just not true, Sheeva has way more than armor moves going for her. That's an oversimplification of the character, Stryker checks Sheeva and Sheeva checks Stryker.
If Sheeva's throwing out random fireballs and trying to zone him, she's not fighting Stryker right. This is like spending the fight trying to zone Smoke or Raiden, it's asking for trouble and it's not how you fight the character. That's a non-issue really.
Also, unless the Sheeva player is being really predictable, you're not going to be roll tossing out of telestomp on reaction. The odds of doing an enhanced move at the exact same time as another player are very slim(as you said above), it wouldn't make a match up move from even to bad. Do you want to know why? If anyone does armor at the same time as another character, it will cancel out both moves..
Sheeva can punish any grenade tosses with a telestomp, which gets her in and up close, they're pretty much equally slow/fast in terms of speed. Stryker isn't going to be running cirlces around Sheeva up close, especially with that armor of hers.
They can both counterzone each other, Sheeva with telestomp and Stryker with roll toss.
Gun cancels can evade stomps and gunshots can sometimes punish predictable telestomps, but if people get predictable, you can punish everything.
Her 2,1,2,f1 grab n punch can set up a throw attempt, fireball etc. if she hits you with it crouching, it jails and she gets to low grab you and get a 40+% combo. Her mix ups are of similar speed to Stryker as well as her damage and overall normals.
This also doesn't take into account that Sheeva can steer her landing spot for her telestomp, meaning she can land behind Stryker, on top of him or in front of him, opening up greater set ups and mix up potential, not to mention it's an unblockable. The mind games of Quan Chi's stomp, but not full combo punishable on block.
The only time I'd be using a fireball against Stryker is if he's throwing a grenade, that's a favorable trade for Sheeva as her fireball is 12% and Stryker's grenade is 9% or I'd do down 4 fireball up close where he doesn't have time to counterzone.
The only way this match is a problem for Sheeva is if she plays carelessly and predictably, but that's the case with everone. They both have to work just as hard to beat the other.
I've been on both sides of this match up countless times against AU IM DIGIMON and against PoliceBrutality and others for months on end. Stryker can't bully Sheeva like Cage or Kabal can, those are 6-4's for Sheeva, not Stryker. He's not on the same level of difficulty as those two characters for her. They might not agree with me though, but this is my assessment after playing some of the best Sheeva and Stryker players I know.
I'd be willing to discuss and explain any and all matches in my chart and will explain them to the best of my ability.
