Like most, I’ve only played a few days so these numbers are FAR from accurate. Still, it’s fun to put numbers on MUs, so here’s my chart:
Jaina vs Grave: 5-5
Looks completely even to me: whatever she lacks in reversal, she makes up in zoning.
Jaina vs Geiger: 3-7
Jaina’s hardest MU free as he shuts her down completely. Geiger’s super can punish for 2 damage any arrow on reaction, stopping her from zoning entirely. He can also jail her with Bs and punish any try of jump in with C, leaving her basically no options as she can’t do the same with her own C. He can also apply ton of block pressure damage by getting in at any moment with jA or jC almost for free as her jA seems to fail to air to air him, her only option is a jB on hard read.
Jaina vs Setsuki: 5-5.
Setsuki’s B stops Jaina from zoning too much, but Jaina’s jB stops Setsuki from going in the air too much. So it looks to me like they both sort of stop each other’s gameplan a little, but nothing too severe on either side.
Jaina vs Valerie: ?
I don’t have enough experience to say anything yet.
Jaina vs Rook: 6-4
She wins the MU, but in my opinion it’s far from unwinnable. Rook has a hard time getting in, but once he does Jaina’s self-hurting reversal makes every guess heavily in Rook’s favor. I personally find Jaina’s jA pressure expecially helpful in this MU though, so that’s why it’s not 5.5-4.5.
Jaina vs Midori: ?
I don’t have enough experience to say anything yet.
Jaina vs DeGrey: 5-5
Similarly to the Setsuki MU, they each stop the other from doing something pretty important in each other’s gameplan. Jaina’s B stops DeGrey’s B shennanigans for the most part, while DeGrey’s jSuper stops Jaina from throwing air arrows. On paper it seems like DeGrey got the best end of the deal, but the MU still feels even to me.
Jaina vs Jaina: 0-10
Duh. Please buff.
