At least make it so it is IMPOSSIBLE to lose more LP than you gain.
What purpose does this serve?
"The system thinks you are not qualified to be in the ELO you are currently placed in, so we are going to give you considerably less LP than what you gain in order to put you where you belong."
Ok...let me just drop down to the rank you think I belong...
"You have lost too many games to maintain the rank you are currently in."
Okay let me try my best to win.
"Here take 15 LP."
Thanks, I also won 5 more times, help me out?
"Here is 75 more now you have 90."
Okay...I just lost 1 game.
"I TOLD YOU THAT YOU DONT BELONG HERE GIVE ME BACK 21 LP RIGHT NOW!"
But I just won 5...
"GIVE ME MY LP BACK!"
