I don't want to get too much into what you said because I feel it would get into super theory fighting.
But with the lightning strings your opponent has no reason to mash buttons. Just wait for the backdash and chase. You put yourself into a situation where you eat mixups or better pressure and you have may have to make hard reads.
F1 and f2 getting beat by quick low pokes.
I hope when you do ex shocker that's for gap punishes or you're talking about risky, costly guesses.
I don't use displacer so I can't comment on how good teleport is in certain situations.
The common thing here is raiden doesn't have anything that's good and reliable besides anti airs and even then that can be shaky ground.
However, with that 6f mid he had a nice reason to press buttons.

(I really miss it

P.s. Good luck in your local!!!
