loss forgiven

So im in bronze and i had 98 lp in b3. I won 5 game sin a row to get there and 6 games in a row with 1 loss in between. Next thing you know i get two afks in a game. Next game i get another afk and im at 58 lp now. I seriously think riot should give a loss forgiven for afk that arent in your same party so duo people cant cheese. Its just annoying when all your hard work goes down the drain due to something you couldnt control. I mean now i have to win 3 games in a row or 4 just to get to my promos which i was so close to.
