Lp needs to be fixed

So I made it out of B5.... For the 10th time this season. I have no problem getting out of b5, but when I get to b4 if I lose 1 game I lose 24 lp. This just happened tonight where I won 4 games in a row to get up to 24 points then had 1 game where we had a troll and I'm back down to 0. I'm not sure how it can be fixed even though I have some ideas. However, something needs to change.
