Playing the AI can develop bad habits, that's for sure. Computers don't understand mind games the way a person does, so they are a bit more predictable. Since the AI is less aggressive, you need better defense against a person.
On the other hand, you can test to see if the combo you just discovered in practice mode is guaranteed or not. The AI might be flawed, but it understands air control, and can always shake out of stuns (okay more like 90% of the time).
At least the AI punishes you for unsafe moves, that alone makes it good for teaching safety.
Will all of the inherent flaws of the AI, it's still 100% better for practice than playing online. It terms of developing bad habits, online is far worse.
Back on topic: I practice specific situations that give me trouble. I like to practice with the AI on what I consider bad match-ups for me. Mostly, I try to find counters/evades to the most commonly used move. Generally speaking, the AI favors the same prime moves that people do, so this gives a good way to deal with said moves.
Slightly off topic: If astaroth does 6k CH, 2B+K A+G, is it guaranteed? In all the videos of astaroth in matches that I've seen, I've seen this simple combo over and over and not once have I seen anyone ever get out of it (provided that the moves are inputed as soon as possible). I recently picked up astaroth and his ground n pound game is insane with all the throws that he has. My one and only SC buddy is really pissed off at my astaroth LOL. Right now, he's convinced that he can somehow get out of that combo listed above. I'm pretty damn sure he cant :) Can someone confirm this for me?
LOL it's so funny when the 6k CH comes, my buddy starts spamming random buttons hoping to get out of it. I know this because I can hear him smashing the buttons LOL. And the next thing that follows is "THAT MOVE IS BULLSHIT!!". He gets even more pissed off when I get off a 22_88 B4 2 8 B+G. The damage on that aerial throw is fucking insane! He's also convinced that he can somehow aerial control out of that grab, but so far, he hasn't done it.. Is that combo also guaranteed?
I'm almost 100% positive that those 2 are guaranteed, the only reason I'm asking is so I can say, "I told you so".
