Decrease LP gains for premades in Dynamic que
Seems to me an easy fix to Dynamic Que is to just to have a system where the more party members you have the lower LP you gain and the more LP you loss. While those who solo que and go against premades will be able to gain more LP and loss less LP depending on the size of premade.
This would satisfy a lot of people who whine about dynamic que and help to buy time for a real fix from riot.
