I appreciate that Pwyff asked the question "what do we gain from Dynamic over SoloQ", I do NOT appreciate Socrates' bullshit non-answer of dancing around "oh there's MANY things" and basically just saying "people are less toxic". What do you base that on? And even if true, that should NOT be an overriding factor for such a major change. Oh, you can have a "fairer" system that is more toxic, or a bullshit system that is less toxic, which do you want?
Also, I agree with GBay99 & Scarra, that role selection had MUCH more to do with some of their stats than "Dynamic Q". I'll say right now, that if it goes back to "5 random people, call your role" (or even MORE than 2 role options before queue) then I'm done with ranked. Nothing in the conversation around the 15 minute mark explains how dynamic queue was a GOOD idea and an "upgrade" over what was before.
