I don't blame you for listening to some of the ridiculous posts made in the Killer Frost forums about how op and 'viable' the character is but she really is not. I would not consider weak zoning, a safe slide that is still negative, no air footsies and a d1 that's advantage on block but has no range tools for making a Top 10 character.
I can see how she may be good in a casual friend over your house playing for fun way but in a tournament I do not see a character that has such weak footsies that it'll probably come down to hitting a parry to open someone up as good
I formulate my own estimation of a character based on my examination of them, not via the opinion of others.
You conveniently ignore all of her strengths.
- Her zoning is FAR from weak. Her multi-hitting daggers and Iceberg are very powerful in MANY match-ups
- Her slide is an amazing anti-zoning, footsie, and wake-up tool
- Her vortex is among the best in the game. (Possibly #2)
- Her D2 and F3 are both very good
- Her parry is a game-changer against certain characters
Frost has her weaknesses, but she is never out of a match with her vortex. How many times did SonicFox come back with Batgirl's vortex? When you have a vortex THAT good, the character is a threat.
