Remake: Losing lp if your premade don't connect to the game

Hi, my premade got bluescreen while we were in loading screen. Our team decided to remake (understandable), but what I do not find fair, is that i lose lp and mmr. I understand that there has to be some kind of punishment, but if I decide to duoq with some random guy on the internet, he has the power of my elo. If i am on 0lp he can demote me, and I can't do anything about it. remaking has pretty much no impact on the other players in the game, they will lose x amount of mins + 3mins. Riot told me it is because some people abuse the system and I find this weird as hell. Premades can dodge champselect and the punishment is - 3 to -10 lp and 5 to 30min wait time before you can q up again. If you dodge in champselect it is only the guy that decides to dodge that will lose the lp, why does it have to be any different if it is a remake?
