So me and Vak played for hrs lol. We ran each of Kitana's variations vs Pyro. RS is definitely the variation to use in the MU and wins against Pyro. The reflect is such a wonderful tool in the MU. Tanya pretty much dictates the match but the reflect is seriously a threat in this match. Once Kitana has the life lead, she can sit on it comfortably, and Tanya has to come in. If Tanya has a life lead, Kitana has to go in, but it's somewhat easy to get it back since the reflect and lift are good tools.
Assassin is a 5-5. Not having a reflect SUCKED. You have to walk your way in now and can't counter zone. She can't even punish fireballs with ex assassin strike on reaction. Thankfully, assassin SEVERELY out damages her lol. Ending combos with assassin strike is a must because you don't want Tanya away from you at all.
I had the most trouble when I was using Mournful. Tanya laughs at the zoning with her zoning. Trading with the projectiles are HEAVILY in Tanya's favor. No real conversion off of air trades with glaives, giving Tanya less fear of kitana in the air. Shadow kick and ex shadow kick are good moves to get in tho
I recorded all of it I think. It'll be up tomorrow afternoon
