How many people actually play their main, but not other characters?

Just wanted to know this. Because i am one of those people. I only play my main (when i get the chance to play after work) and that is a major reason why I'm still at my skill level. So at matches i sometimes find myself complaining about "how cheesy is this" but then stop myself because i know if i just play the opponents character or just lab, it'd be a lot easier.
