I didn't "come up" with it. It's fact. A proven fact at that. Idk man, it just seems to make some sense... perhaps. We'll see I'm gunna get to work on it.
When it comes to "safe" and "unsafe" it's different in DOA. You have characters like Kokoro where you cancel out certain strings into other it'll make a move that is normally unsafe into semi safe(or safe). Free cancel can change some sh**.
You have characters who do unsafe move, but there is a follow up that allow it to be safe. You can may be able to only punish it with just a strike other than a throw. It can be some confusing sh** indeed. But in the end. Online still f*** it all up. Ain't that about a butter biscuit and gravy sandwich with some chops on the side.
