Blizzard: Why the fuck do you get a leaver status for getting kicked from a dungeon?

Seriously. It's bad enough that you can get in a group with fucking clueless assholes, but you're going to go ahead and give a matchmaker cooldown to someone that gets kicked?I've literally seen a vote pass to kick someone because they got the pig on the 3rd freehold boss.I've seen a vote pass because a dps asked if they could do the world quest boss.I just got kicked from a group because our tank decided to pull an entire room, and I couldn't heal him while I had a 9 second stun on me.So, I reiterate, with how toxic the community can be, why the fuck are you giving matchmaker cooldowns to people who get kicked?
