Why do you get a loss for jumping queue while you are in your series?

I honestly do not see why you should. This is most likely the time when you are gonna want to leave queues (if there are trolls) and that is a pretty major punishment for something as small as leaving a queue. I understand time bans and even the small lp losses but seriously, a full loss? In the dumb three game promotion that we are forced to do anyway? This is really stupid. Please fix this and possibly remove series as a whole (or we could just go back to mmr).
