To add to what the above people wrote. Online experiece vs offline experience are different. DoA4 I would argue is made for online, SCIV not so much. I speak of the dreaded lag, & certain moves like GI & GP I would suggest you pay attention to in online play, particularly if the connection is questionable.
Also some common sense, what are the strengths of character
X? Speed, power, defense &/or defensive moves, can moves flow easily from one to the other (
Maxi as an example here)? The advice I always give is pretty simple, try all the characters & look for those character(s) that're "you" & look for those people who use "your" character(s) well. Ask them to teach you or play you, the worst things they can do are either ignore you or say "no". Also, if you can record your matches (
been awhile since I was on this so I forgot) try & do that. Just as boxers study tapes of their old matches, do the same. Look for those things you tended to repeat &/or that your opponent capitalized on & in this case do the "what if?" game by looking for those things you could've done different. During a match, don't panic or lose your head; because once that happens you neither regain the initiative or win, that's just the way it is.
I'm pretty systematic; practice the moves, look for what flows into what, & then look for those who use "my" character(s).
The technical aspects I'll leave to people like
KowtowRobinson &
Tidelleaf (
how you guys study that stuff without getting bleary-eyed or a headache is beyond me). Hope I didn't ramble too much, I'm getting old
That which is manmade has within it the seeds of its own destruction.
