@ Riot, you you can not "fix" dynamic que for solo que players
Yes, a majorty of LoL players like Dynamic Que
But by Riots own survey there are a whopping 15% of players who prefer Solo Que and half of those actually hate Dynamic Que. That's a sizeable part of the comunity and it doesn't even include the player that like Dynamic Que but would use Solo Que as well.
Yes, there are a lot of things that can be improved about Dynamic Que
But no matter how much you improve the experience and appearance for solo players you can never fix the fundamental problem, because it's the very nature of Dynamic Que: Solo players do not want to play with or against premades, period.
There is only one solution to this: Make a true Solo Que!
I recon the demand is greater than even TT, HA and RGM combined.
