I've been playing her as my main. Trust me, she's up there. Amazing pressure, decent pokes, great damage, awesome mixups (214A~B crosses up and the opponent doesn't autocorrect when they jump?!), and what may be the best Super in the game. I'm not sure when her Big Bang Smash comes out, but it punishes everything. Full screen. I feel so happy punishing tech rolls with it, lol.
btw, I don't have much Hazama experience as Tager, but I assume you could confront him the same way a lot of people do. Camp him. Not strict camping necessarily because Sledge/Spark Bolt will catch you at some point. You just gotta know when to approach, but make sure everything is on your terms. They always are against Tager after all. Good thing to remember too, the timer is almost always your greatest ally in this matchup. I don't play Hazama, so I can only give general advice, but the rest of the cast treat him this way too. Few things make you feel more helpless than Tager vs. Fu-Rin-Ka-Zan.
