You're a joke for even thinking this.
The ability for a team to talk on vent/teamspeak has HUGE advantages in coordination. I was JUST against a coordinated premade team while I was the odd man out on some stupid 4 man premade in this dynamic queue crap.
It was UNFUN, and UNFAIR. Premades help their own people, premades blame you for everything while I suffer pro-coordinated teamspeak ganks in my lane from the enemy premade.
Forcing me to play against coordinated teams as solo while having a 4 man premade was the most toxic thing in the entire LoL, but atleast it was restricted to normals only.
So blow it out of your ass with your lies. Riot literally ruined the entire credibility of supposed competition in this game.
