I’m with pertho. If someone smacks you down with a multitudes of characters like that then one of two (or both) things are happening:
A skill/knowledge gap or
The player is using or has noticed some bad tendencies in you and is exploiting them. This could literally be anything from bad punishes to bad spacing to bad reactions in certain ranges, it could be overuse of the same hit confirms or poke strings, it could be that you like to poke or interrupt at the same point in a string (a problem I have that I also use to take advantage of others)
It could be one thing or many things.
Best thing to do is look at your replays and first look at how you took damage directly. Walking into pokes, getting confirmed, getting counter hit, white chip, real chip, any way you take damage look at it and ask yourself why you took that damage.
Next is to ask the question of ok, now that I know HOW I took damage, why did I allow my opponent into that spacing to give damage in the first place.
You may see that you have a weakness to a specific tactic or tactics, like dashing or jumping or ex DR or blah blah bla.
That’s the very basics. Off shoots tend to focus on the micro side of those kinds of things.
As an example, a piece of advice that highland has given me over and over again is to have better meaty setups because he tends to jab me out of my wake up pressure a lot. Well the advice didn’t fall on deaf ears, but some of my characters just have bad meaties air I’ve on,y been playing them for a few days at the time… etc etc
But when I get a character that has easy meaty pressure… like ed on certain knockdowns, I can pressure much better and convert that to round wins.
So any small thing that you can make actual improvement in will help your results. The big problem is when you realize that mental focus only goes so far so you can on,y look for certain things and that causes either fatigue or a focus break. Like you see that your opponent t is getting free jumping all day so you focus on AA and stop them cold. But now they switch to dashing or fireballing and now you are “free” to that stuff.
That’s the main problem I have in this game… till I REALLY get to know a players style and rhythm. Of course this all comes back to what highland said earlier. When you first use a character you won’t be reacting as fats with them as with other characters that you know better… even to the exact same situation. So like I AA WAAAAAAY better with Urien than I do with Akuma even though Akuma has way better AA than Urien does. I just know Urien very well and can sniff out jumps 3 seconds before people jump just because of their rhythm and spacing.
So when dude said “idk you’ve only got 3 days” he’s saying he can’t critique your ACTUAL skill because you haven’t developed that skill yet. You need more time to get to your higher level of potential with that character, which I guess is obvious, but when you ask the question he’s just going to be thinking in a higher level. He could give stupid platitudes like get your meatiest better or stop jumping or you dash from this range every time, but those are issues that may not be “you” but instead are character inexperience that will sort itself out in a couple of weeks.
