I've been toying with 8WR for a long time now, trying to find some way to do that elusive 8WR move from absolutely anywhere, and it just doesn't exist, unfortunately. But you can do it from neutral, and you can do it from moving in any direction. To do it while you're moving, just roll the stick over to the direction of the move you want to do and hold it as you press the button. I've been doing a different input for using this technique at neutral, which is less instant and more I'm in 8WR but you can't tell I went into it. Notably, my way works with every character, every move (as far as I know).
This little tech has improved my Leixia gameplay quite a bit. For example, I like hitting people with run-up 22K. So basically, 663[2]K. It is extremely effective. I execute 11A the same way. I also like to do 22B+K while I'm just standing there, auto-GIing on a read, and getting a launcher combo from the follow-up. But by far, the most useful thing for Leixia I've found by toying with 8WR is that I can get 22B to not double back on itself. You know, 22B makes her move in the 8 direction and vice versa, and that often causes you to step out of moves only to move back into them. The input is 22369[8]B. When you do that, she continues moving in the desired direction with a pause only as long as your input is slow.
So yes, toying with 8WR is a great thing indeed... but I don't think i8WR really exists. For all you know, you might just be entering 8WR when you do that motion.
