Riot, if you seriously think that having any number of people in a ranked premade is fine,

then why not allow "Dynamic queue Treeline"?

Beforehand, the argument was that "A duo would take up 66% of a team, and is a bad experience for the third person."

Since you now allow 4 man ranked premades, which take up 80% of a team, that argument is pretty much invalid.

I play ranked pretty much exclusively solo (maybe a duo game every few weeks). I happen to like treeline, and would jump at the opportunity to play it ranked as a solo player.

A large part of that is that a 2 man premade flaming me is slightly less annoying than a 4 man premade flaming me.
