A suggestion for ranked.

I don't think the lp you lose from a lose should be able to be more than you gain from a win. I remember last season I got placed in Silver 4 and dropped to silver 5. I made 5 lp for a win and lost 20 for a loss now I dont think this is fair because it gave me like a 10% of getting out. I would win 4 games for the sake of the argument in a row and lose 1 and bye bye lp back too zero. Its just my opinion but I dont think this is fair. Thoughts?
