Except if he "hurr durrs" with his teleport he gets full combo punished. And his best mid string, f34, only nets damage 1 time per match
I think you will not be able to convince salted people. There are many people beaten by the most basic stuff - you do not need to highlight the real threat of Scorpion if "reacting" F32 or punishing teleport is the source of the pain.
At least my friend is only pissed off by walk back B1 punish lol. He levelled up grinding the match up with me. First 100-200 matches he always got caught by F32 and teleport lol.
And I also get caught by it against Scorpion as need time to get used to it. But no point complaining about it.
You need to learn any match up. Almost every character has something which needs to be labbed (a punish timing, a string, etc.).
The discussion here is on very low level stuff though.
I do not even know what is the point of the complaining. Scorpion is a good character. No one should surprise it is a difficult match up for everyone.

We can go to at least 10 other character's forum and write the same as they are also really good and difficult to play against.
