Problem with -10lp for 2nd dodge

So today I was in a lobby with 2 players who played together in the previous game and were not too fond of each other. One of them banned the other's champion and so the other guy locked in Soraka ghost/cleanse top and declared he would int if nobody dodged. The issue in my case was that I had already dodged another lobby with an inter so if I dodge this game I get -10lp. Since I get -14lp for losing it is basically the same as dodging and so the only positive outcome in this situation for me is for somebody else to dodge. This forces me to also pick a troll champion with ghost/cleanse to try to force a dodge. If they made the lp penalties something like 2lp and 5lp then maybe I would just dodge and save my other teammates from the griefing Soraka but the way the dodge rules are the only logical play I have is to pick a troll champion and try to force a dodge. Obviously this is ridiculous but the way the rules are I don't have any other choice since winning a 4v5 in diamond+ doesn't really happen. This system needs to be changed.
