Why Dynamic Queue in Ranked is Toxic

While I haven't touched ranked this season, I have played a number of normal draft games with the new champ select. Now that people are allowed to group as 3,4, or 5 in ranked, here is one huge problem players will face:

Group toxicity. It was already bad enough to be at the end of a duo queue's flame, but it's even worse now. People are now allowed to play ranked in larger groups, which sucks for solo queue players. Not only do these groups have an advantage in communication (usually) but they also tend to gang up on the solo queue players when the team is losing (or not even - toxicity can spawn from anywhere, really). For example, if a jungler who's solo queue has all his laners be a 4 man queue, then of course that jungler will be the one blamed whenever something goes wrong. If the jungler ganks bot, gets a kill, but mid and top die solo 3x.... that's on the laners, not the jungler. The laners have no excuse to whine and bitch at the jungler just because he's not in the room or the skype call. It's almost as if Rito doesn't want anyone to solo queue anymore.
