Skarlet... hmmm
I love her, she is awesome, but she has some weak spots. Her mix up game is alright, but a lot of her attacks have slowish start ups and are easy to pick up. Her two pop ups are special moves and SLOW AS HELL. Makes me mad lol. Her double daggers give good juggles but I read that they are patching the second dagger so it's slower. Why? I don't know, that's one thing she has going for her. Her bloodball is pretty useless, I only use it if I have almost a full health bar and the opponent is almost dead.
Overall, I'd give her a 7.5 pre-patch. Wonder how different she will be since they are nerfing her >.<
