Been in the lab with her for about an hour and I just wanna say she has pretty excellent but reasonable frame data.
10 frame mids, 12 frame mids, bunch of -2 strings(perfect for stagger mind games), gapless plus frames off ex fireball, stomp mind games, overhead seems alright, sweep too. NRS really came through for Sheeva this time, she is fast in relevant ways. Telestomp start up is pretty quick so she'll have a legit counter zoning option on deck.
I'm pretty sold on her ex fireball, stomp mix ups, quake and anti-air grab primarily because her down 2 doesn't look that impressive and down 2 is 9 frames, anti-air grab is 10 so not a substantial difference plus it can combo.
I'll have to try the others later, but she definitely feels like a labor of love <3.
