I'm going to unlike your post after watching those vids lol. You seem to know your shit but you don't know your shit. Maybe you just need better sparring partners, someone able to take you to the next level.
Thanks for posting those videos though. A good example of a player unable to set up attacks to land but everything Gruff said here is spot on and he even has an idea of how to set things up (see his post about throws). 4k+h is the best get the hell off me move in the game. Couple that with 1k, 1p (pk)3k and her 4 and 6 frame throws she is an awesome turtler. Her move list is pretty much all killer. His point on her throws (also 44p+h is 6 frames, which pretty much means it can punish everything. Even if they do a safe move and not attack or crush straight after it).
It's not a bad thing, you must know the basics as you know your shit. Just need to take the step fully from being a beginner to being intermediate. That Mila shouldn't have beat you at all.
