These are opinions not to be interpreted as balance discussion.
Here are the things I like about valentine:
She has two lows, cr.lk and cr.mk, that work quite well together.
Backdash iad j.mp is a stupidly good pressure tool in the corner, and j.mp is just great for pressure all around because it starts up quickly and eqch hit is so drawn out it messes with th combo tempo.
I like that she has an air fireball even though its generally an awful tool.
I think I like s.hk?
I like her double jump and her j.hk, nice mobility and a big red hitbox.
Bypass xx scalpels has been thoroughly nerfed, but I still like to use it, it gives me full screen control I can't get anywhere else with valentine, just gotta be smart about it.
Things I don't like about valentine:
I HATE her airdash, its so floaty and slow I can't stand it. It shuts down the tempo off the game if you let it rock for more than a few frames and just feels like meh.
Her j.lk is also now on my shit list because it has almost no use, it's a giant sign that says 'reset here' and the resets you use it for feel so slow. At best you're gonna do a double cross under but the move itself is so one dimensional and boring.
Her resets, I dunno if I'm just so used to them that I am no longer entertained by the novelty or what (unlikely though because I still love fortune resets). They are either slow, predictable, boring, or repetitive to me. Any j.hp reset is gonna be slow, and fast fall reset is boring, any j.lk is predictable, and on there own they just annoy the hell out of me.
She feels slow. Fortune feels twice as fast in every aspect.
J.mk, don't need a reason because it looks and feels uncomfortable for me, its the quintessential floaty slow valentine move.
Oh yea and not haveing a reversal kinda sucks, it sucks a lot.
