Just because he's selective about the matches he uploads to make himself look good doesn't mean he's consistently getting perfect victories. Last time I bumped into him it was 4-1 in my favor, and I'm garbage.
So long as there were enough recovery frames on the cancel animation that it had to be a considered feint and not just some nonsense that replaces his idle stance then I wouldn't be opposed to it.

Second, pretty sure @WAZAAAAA has uncovered more competitive DOA tech recently than the rest of the community combined by breaking apart the PC version.
Third, can I assume by your description of DOA PC players that you are among them?
Fourth, irony...
