I hear that, I'm constantly trying to get people to stop those bad habits as well. The most common ones are DP overuse, button mashing, and excessive chicken blocking lol.
Edit: Whenever I get on ranked, I usually get paired up with the same people over and over again, so I don't get much hatemail or rage quitters. Most of my "incomplete games" stem from the countdown glitch (6 of them, the other 4 are from people who really RQ) lol.
