As a solo player for 3 years, dynamic que in ranked has really ruined the fun for me.
Yes, ranked has toxic people, trolls, afkers, feeders, and even the good stuff, but before dynamic que I would think: "It's ok though, everyone is in the same boat as me, let's try again."
But now with dynamic que, I can only hope not to get premades. As a solo player, being in a premade or going against one is the least fun for me. Especially when you get a toxic/troll premade, hoping that the next one won't be as bad.
I am at a disadvantage cause I prefer to play this game alone (and my friends aren't gamers so they won't play). Now its hope to get a nice premade or go against a bad one, or find people and make a premade of my own.
So now when I log on and see no one online to que up with, it's like: "dam, here goes nothing". Lol!
Anyway, I'll prob still play ranked until I'm fed up, but just sharing that as a solo player, dynamic que in ranked has really ruined the fun for me.
