I dont really understand the question... Reptile previously had no frame traps, even on his +2 strings his best poke would still get beat out by 6frame d1s. So now you have the mind game because your d3 is now 5 frames after 1, 21 or 12. Now they have to respect it and you can mix it up with the overhead. If they try to counter poke you / jump out, you win and now have a 50/50 again. They won't be able to get armor out in 5 frames, they might be able to backdash.
Its another tool, doing a 50/50 off jump ins every time isn't something I like to do especially when hes gained the ability to condition opponents. I mean take into consideration the Lui Kang MU, Reptile couldn't get out of the fake fbc pressure, now he can. Shit all the strings Rep has that are -2 like 14, 34, Lui Kang can't do anything but block because now a d3 follow up turns into 9 frames so at BEST LK can hope to trade with a counter poke.
My main training partner is Scorpion so his d1 beat everything Reptile had now he has to respect it.
