I main Bedman, and I am way too used to using Task A' (the projectile that teleports him) to get in. What made it obvious was that I was recently fighting a Potemkin, I tried to use Task A' on him, and whaddya know he blocks and I get Potemkin bustered all over, I stop doing that for a while but I try it again, he blocks it and suddenly he comes Potemkin busting through, so I quit it for the rest of the match. So later on the match is tied and we're both low health, he knocks me over so I try to use bedman's overdrive reversal, and whaddya know what move do you think comes charging through and triumphs over my reversal? Potemking buster. Realistically I should have backdashed.
So basically my bad habit is that I sometimes use unsafe moves to play aggressively, which is a pretty bad habit indeed.
