LP Bank/Pool

Hey everyone this is my first post but I recently came across this problem recently and thought it would be a good to implement some kind of fix into league. Playing ranked is a rewarding experience but being stuck at 93~99 LP and having to win a whole nothing game just to get into promos is a drag. Advancing to the next Teir would take up to Three wins in a row if not more. I was thinking that instead Riot implements some sort of LP Bank/Pool that would accumulate up to 10LP give or take in order to grant it to you when you need it the most, AKA when stuck in high 90's LP. This might seem stupid, but playing a WHOLE another game seems way to redundant just to gain the tiny LP ( 3-7)(when you would earn 18-25 LP for the game) needed to get into promos. The pool can accumulate from playing league games in which you don't get reported, leaving a reward of sorts for those players that are nice/good/friendly in their games. Its an incentive to help those climb faster/better.

This might seem stupid but I have had this happen way to often to my friends and I, and I think some sort of fix would be nice. Im open for discussion so leave a comment below if you want to change this in any way! Thanks for reading.
