Why do you play your main ?

I main K.Rool and Yoshi. I play the croc because I learned the game with him his animations are awesome and I like heavies but I don't like getting gimped at 30. I play Yoshi because I like having a combo-brealer that isn't super bad and because he is easy as fuck.( I would rather use my practice time to learn marchups, get consistent and actually see progress in less then an hour.) How about you?
