Almost every matchup I have against people ends up silly. It always ends with the other person having to do ridiculous things they never would.
5D is good because it has a longer active time. So I can start it up earlier, knowing that I can still catch your move with the very end of it. And if you don't do anything, since I timed it to be the end of the counter, I will be on the very end of the recovery, which maximizes my chance of escaping unscathed.
