In case anyone reads this and thinks my opinion is worth anything..
There can be no debate about Sky Drop, it has always been broken. In fact, every character in the game (except for one) is immune to sky drop during their upwards jumping arc, regardless of position or the type of jump. Easy way to get a general idea of how that works is to do 1,2 and skydrop. it will always whiff, whether midscreen/corner, NJP etc etc. This occurs from about the midway point of the jump to the peak, so even on a correct read you will
never hit your opponent. I have witnessed this cause Michaelangelo and others losses in tournaments. While fixing that would not solve his issue on wakeup, it shouldn't.
As for a faster poke, I agree it would be nice, but i'm not sure its necessary. I have not played against a liu kang or anyone else that can do a so called block infinite, but i'd like to if anyone wants to demonstrate to me. PSN tag is Gustavness, I'd like to see if there is really no escape. send me a friend invite and let me investigate.
There are also many things that people think are "traps" or "safe" options but can be punished by his 6F iNJP relatively easy. For example, D'vorah's shoulder rush string into puddle can be iNJP into 36% quite easily, and it is easy to see. In fact, i believe quan is the ONLY person in the game that can use his iNJP in this fashion, and I never see anyone use it. wakeup iNJP is very effective, you can ask
@AoK Ryan how he feels about it
