The best thing about having a Cmd Grab or a scary grab game, is people losing to the fear of the Grabs rather than the grabs itself .
So what that means is they going to be mashing, running away and jumping all over the place because there fucking terrified.
So if they in that state before the match begins they are already conditioned and your job as a grappler is done for you, so don't do the grabs and finish your staggers and stop cancelling Cmd grabs off pokes but instead use the frames you got to catch them with a normal and full combo.
If opponent decides to just turtle then boom introduce them to Suplex city.
