I struggle in some matchups too but In any game I compete in I usually run two characters. In this case I have Scorpion to back Frost up if I need to (in serious matches). That said she's far more viable now than pre patch, at least now I can fight back if people get in my face and decide to try to hit buttons recklessly. In any event I like FB in concept since it is loosely based to Cyber Sub but I think the character could use a couple more tweaks. It's like the designed her to be a specific way, but the meta made it to where she didn't really work 100% too well with it and in some cases used to be counter productive to herself. Now she has some added goodies but she has a strange pacing.
