I'm speaking in general with all other character's I've tried but Tina is a very different experience as a Kasumi player
Helena & Christie is slightly overrated. If you really want to test yourself, pick up Eliot, Brad or Pai.
Ayane's difficulty is also overrated. I only said that because they both play completely different than Lisa. Btw, nice DogeAkira lol
I tried learning Pai, but she didn't click. Eliot has an execution barrier for me (I suck). I hate Brad too much to use him. So I'm trying Kokoro again.
How is Ayane's difficulty overrated? Anyone that picks her up have no idea how to utilize her. Brad also is definitely tough. Kokoro's genuinely a decent choice for a sub character.
