Interesting, when I get my SD card back, I'll start looking into crouching and seeing if I can come up with anything crazy with the crouching. You would think it would haven't any sort of weird mechanics, but go figure.
That being said, my desync is more than just blizzarding out of dtilt. After making my DSC stuff, I was looking for a way to go directly from an anti air game seemlessly into grab setups. This desync seems to be the fastest way to do that. I've been testing it using Bair/Uair walls straight into grab setups, blizzard or IB, it doesn't matter. All of it sets up to the grab setup situation. Given complete mastery of it, it might be game changing.
Also: You really ought to try sharing some of those tips. I mean, I'm relatively certain that we're close to maximize the fastest setups possible, but I'm sure there are a few things left to look up. I've pretty much figured out everything out of shield drop and landing lag. I'll look into crouching next, but I am not sure what's else to look into.
