Seriously considering dropping Val.
She literally does nothing good. In basically every regard, she's worse than every single other double-jump character in the game. So what if she has a gimmicky airdash? It doesn't let her do anything that Filia and Fortune can't do better, and her neutral game is garbage, since her pokes are shit and her actual air movement speed is fairly slow. Add sub-par damage to that and... yeah, there's just no reason to pick her.
I was going to let you wallow in self pity... But I'm a bit bored right now... Things that val is great at or just very good:
Corner carry off just about anything. Cornered characters are a shell of their former selves.
Run into st.lp is a great footsie tool. Mix it up with a throw or a low after the st.lp.
She converts easily off of any dp assist in the game and has good resets.
She makes space easily with double jumping backwards to reset the neutral.
She can airdash cancel all of her air normals for better spacing.
Great low/throw game that filia needs meter for.
Her air pokes have tremendous priority when used from backwards jump, just cancel into forward airdash to turn your high priority defense into offense, call an assist anytime during this to pump up the pressure.
Protect assists well with ground shuriken or air savage bypass xx scalpels if the opponent is hitting your assist.
Extrememly safe hitconfirm.
Can get higher than any other character in the air and call assists (even if YOU dont know how to cheese this up, its still a great tactic for her to use)
Probably the best character in the game at turning extremely evasive movement into offense before she ever lands (which makes the tactic very fast)
I suggest watching some euro izzmo games, or even some Clarence Mage games... Actually i think there are some vids of me playing against Clarence uploaded on my channel... Just google dime_x vs Clarencemage... Probably.
