Question - A-List Run Cancels Fixed (Maybe?)

[Disasterpiese]

I read that most players hold the block button to do RCs and that's how they were affected? I never did it so I guess it's that. But to my knowledge, the frame advantage was nerfed but I don't feel that difference.

I never holded down te block button too but i also was never +enough to create true blockstrings, for the people who are using this te tech when do you hold the block button after the run input? (Its not viable anymore they say but i want too know for experimenting with the cancels)
