Might as well mute everyone if you Solo-Queue in Ranked now.
I don't know if this is just selective bias at play. But when games with a 3-4 man premade on your side go badly, and your lane happens to be a losing lane. It seems like people become uncooperative and very aggressive. You get singled out by your team, they're on voice comms, and they kind of just... stroke each other with lack of a better explanation? They only help each other and never help you, which makes your situation worst, which gets more rage thrown your way. This gets worst if you play a role that requires the cooperation of other people to even function like jungle or support. Reporting them also doesn't work, and if you even retort while they tell you to go "fuck yourself", you're the one who gets reported by the stack.
I've had this happen before with individual players, for instance if the jungler comes to your lane and you screw up, but now it's whole stacks just jumping down your throat if you screw up.
As much as the new champion select is great, the dynamic queue just makes me want to avoid communicating with my teammates altogether if I solo-queue. I remember Riot teasing a "Club" feature for the client, I would love to see that happen ASAP.
