Ranked LP Change - Theory

What if you could prevent massive LP losses when you are fairly certain your odds of winning are low? And vice versa when you think you have the upper hand?

Could it be feasible to wager an amount of LP in the champ select screen before the match starts? Obviously there could be a limit and restrictions to wagers (i.e. must be at least 15% rounded up and no more than 30% current LP, which can scale with total amount of LP at the time). That way if people you are matched with have a low win rate on a certain champ, you won't feel so bad when you wager a low amount of LP and won't have to dodge. Or if the other team has picked champs that will clearly out-class your lanes it won't be such a detriment to the climb. Also, you couldn't really abuse the LP gains because you could only wager a percentage less than half of your total LP, so losses when you are overconfident can bring you down, but it won't be impossible to get back to where you were previously.

There is possibility to reduce the stressors of troll picks, teammates with poor connections/AFK (if they tell you before the game starts obviously), etc.

I don't think Riot would find this idea attractive, but it's interesting to think about because it could help the climb, and also endorse more competitiveness to not lose LP wagers.

Would love to hear some more ideas about this!

Thanks
