What if longer ranked games led to less LP loss?

(Yeah, this is going to be downvoted to hell)

I feel like longer ranked games should lead to less LP lost as it shwos that you are better than someone who lost 5 minutes into the game.

For example: -Game ends at 0-25 minutes: full LP loss -Game ends at 25-30 minutes: 10% less LP lost -Game ends at 30-35 minutes: 20% less LP lost -Game ends at 35-40 minutes: 30% less LP lost -Game ends at 40-45 minutes: 40% less LP lost Game ends beyond 45 minutes: 50% less LP lost

Maybe this scaling should be less heavy at the end or more heavy in the beginning, but I'm sure you get the idea. If I lose a game at 18 minutes, I must be a bad player. If I lose a game at 48 minutes, I put up a great fight and most likely nearly won.
