Every time someone is fully charging their smash attack from the other side of the stage I have the biggest urge to just walk into the smash and get ko'd on purpose xD
-When I have the upper hand I tend to play with my opponent more than usual. Like, for example, I'm a stock up at 60% and they're on their last stock at 90%. Just because I know I can end their existence at any time I'll use weak moves and pummel-only grabs until they're at like 190%. A few times this has backfired on me .-.
-I spend too much time on For Glory hoping to improve.
-I'm generally less good against sword-users or ranged characters because my style is to run in and pressure the opponent.
-I try to reflect projectiles too much to be stylish when I can just jump over 'em.
-I can't Stage Tech to save my life (Literally).
EDIT: While not actually a flaw, I despise Yoshi. He's so broken! Nerfs all day pls.
