[11] Champion
I tend to put the computer on the hardest setting in practice and fight them for hours. Usually characters that I personally have trouble with like asta or ivy.
That or I practice other possible combos I could be doing. Its how I learned most of my combos xD
This doesn't work, and not because I'm an elitist against the AI or anything like that.
I can tell you right now that the AI for any fighting game is inherently flawed -- either they can't block certain setups, or block all setups -- something a human would never be able to do.
Case and point: Ivy will almost always hit an AI with her CL A+B[A+K] on the second hit for no good reason. Yet, anyone who plays Ivy knows that this move is unsafe/predictable and should be used sparingly. You need to be consciously aware of the AI's limitations, and even then this doesn't come close to actually praticing setups with a person.
