How about you move up a rank every 100 points
100 points at Silver 3, welcome to Silver 2. 100 points at Silver 2, welcome to Silver 1. Lose 15 LP, back to 85 points in Silver 2.
I feel like mid tier promotions grease the ladder towards tilty players. 3/5 is hard enough at the end of the struggle.
Meanwhile good players that smash their promotions skip a number of these pesky games because "they aren't necessary for pros."
Has Riot ever defended the 2/3 promos that occupy 50% of the hate/quit/cry threads on the forums?
