In my experience god ray is best when you throw or hit your opponent away from you and you don't intend to chase. Mostly to build metre (which Kotal has a lot of problems doing it seems) and to annoy your opponent or pressure them into coming at you (if they are not zoners).
I'd never throw it out when being pressured in the corner if I were you.
Except df3 I find as a better option there in like... 100% of situations, unless the timer is about to run out and I need about 2-3% of healing to timer scam them. Even then it would be easier to throw the sword and chip them them down.
Does seem it is 100% useless in the corner which was the only hope I had for the move so eh.
As for Kotal in general, my current feeling is that he's basically a worse version of Ferra/Torr.
An unfortunately apt statement I feel, I might even try out Vicious F/T a bit. They have all the same (actually, significantly BETTER) mixups with all their strings and specials as well as a command throw on top and are just way more safe. They don't get sword toss though, that's pretty much the only thing. Also a way slower run.
Ending a combo in throw/sunray or b122 cancel into sunray SHOULD work. But I'm scared to ever do it because Sun Ray recovery is so high. Throw/sunray is the only reliable setup I've ever found.
Nope and nope.
Throw isn't even close, it is only 37 frames of advantage, so unless you throw them OUT of the corner completely defeating the point.
I've gone through every string, it seems impossible to cancel into a god ray safely, sucks.
