Anything that isn't common knowledge that should be common knowledge would be useful. Like the best way for her to punish lows, what to do after JG, GI, and Guard Breaks, Poke/BA/Advantage strings, when and when not to charge attacks. All of that good stuff. You have my support :o!
But...I hope you don't emphasize her c2b loop. I think that ends up being a crutch for many people new to the character, and they end up picking her or dropping her depending on whether or not they can pull it off (like I did back in February). I always end with C3A, because meterless 90+ damage on a whiff punish is nothing to sneeze at :|. Just my opinion.
I have only found one good use for 4B. Vs other long range opponents(asty,hilde,nm,seig) if your standing just in max range of their attacks you can use the 4b like mitsu's 4b. SO think of it like mitsu 4b that only works at max range.
best low punish is while rising kick or 66k. Use while rising kick if they are close, and use 66k if they are to far to punish with while rising k. Her low punish game is pretty bad.
matters what you jg to what punish you can get, for the most part best punish moves after jg will be 66k,2AB,aa
Learn how to always use c2a, and never use c3a even though it will beat a lot of people. Using c3a is the real crutch. PLay around with the c2a timing. maybe you do something like AA- hold 2nd a-66k-c2a. PLay with the timing of c2a. I dont have any exact strings i just play with the charge time while doing other safe attacks. Learn how to wavedash on both sides. This is actually very very important. Cause if you dont wavedash with hilde characters will get to close to you to fast. And you wont be able to space them out.
After guard break i do AB hold-c2b loop
If someone is close to you, you dont want to be charging. If you get knocked down, you dont want to be charging. Keep people at c2a's range and wavedash away from them. If they break c2a range let go of all charges.
every once in awhile use c4a, but dont use it every match. maybe once a game or sometimes once every other game.
learn how to juggle with 3b be. It is alot easier then the raw c2b loop. easily you can do this loop 100%. And its really good to do for extra damage or RO combo's.
use 66k as your main punish tool. at far range use c3b.
when you start to play around with hildes combo's and you want to know timings i can help you. But you have to have some idea of what im saying before i can tell you. hope this stuff helps
