I've been meaning to say this for awhile Mike, but I always forget lol: I think you should start practicing an all-out aggressive playstyle! I know you have a defensive mindset, which is great, and I don't think straying from it will help you, but imo I believe learning how to be aggressive-counter (ie: Arty's falco) will help you in decision making ;D. Maybe pick up a character that can be aggressive/defensive, like Wario, and playing him in friendlies/$1 MMs? Idk, it kind of worked for me lol. You can apply whatever you learn to that sexy ROB of yours ;o.
Idk, just a thought. And like always, I'M ONLY HERE TO HELP DON'T KILL ME
