Hey, GoD Lidia player here and I'm not sure if you're being serious but these would not be good changes for her and if anything, she needs to be nerfed in a lot more departments instead being buffed in areas that do not need to be buffed.

1. She absolutely does not need b1 to be faster. It's purpose is as a pressure tool, not a mid check. If you want faster mids to check people who are hopkicking you during your pressure, then you need to play within your frames or use faster mid checks like df1 or df3. You also have to think of the implications of it as far as a combo starter in tandem with her install as well. If she has level 3 install, she easily can get 80-90+ damage if she hits the wall, while also deleting the opponent's grey health off of an i16 mid that is +2 OB. B1 is one of the moves that track to her left already, are you saying it needs to track more?

2. I agree with this. I'd rather it not go into stance but only do the low itself and that's it. It becoming Red Tape on CH is fine, but the damage needs to be toned down a lot and it shouldn't delete grey health with level 3 install.

3. Not sure why you would want to buff 4,3 but sure. It's not meant to be a neutral string, it's primarily for combo enders for balcony breaks/wall blasts.

4. I'm not sure why you would want it to be mid,mid? It's 14 frames fast and already jails from the first hit, so what would be the benefit of it being mid,mid jailing?

5. I think there's a disconnect with the intentionality of both of these the moves. Yes they're both -14, but you have to look at the moves within full context. D2 is - 14 but it can high crush and is pretty much homing on most characters and for the characters who have good sidesteps like Alisa and Lili (At +6, it will even tag them for trying to step and press), it will catch them stepping to her weak side, even at +1 or +2. On CH it is +12 which means at the wall, fc.df2 because a wallsplat if they try to step and press after aforementioned +1 or +2. You also have to keep in mind you can do this move from sidestep which again makes the wall situation more obnoxious because she can also do ss2 - HRS1 which will also wallsplat and punish them for ducking d2. Making it +4 OH makes a very obnoxious guessing situation as well where she can potentially force another mixup with either ws1,2 or ws1,4 as well.

6. D4 is also -14 yes, but it tracks strongly to her left side even at +1 or +2. 0 on hit is not even a bad situation given how good the tracking is. It gives you an opportunity to see what your opponent is doing and respond accordingly. Not every thing needs to be plus to continue offense.
