Improving Ranked Solo Queue, with new option

I think I've come up with an idea that should radically improve satisfaction with ranked solo-queue games.

There are multiple inter-related problems for solo queue, that can be solved with just 1, albeit large, change.

First, lets identify the biggest problems, when it comes to having a decent game in ranked

Problem #1: Getting paired with some random schmuck that is AFK for most, if not all, of the game

Problem #2: a team of random non-cooperative people, getting matched up with people who are duo-queuing

Problem #3: making a ranked team, is very very difficult. The mechanisms are not too difficult: However. there is both a lack of understanding about it, and also an unwillingness to commit to playing together as a team regularly.

I myself was reluctant to join a ranked team, and didnt even understand what was involved, until a very good friend convinced me to try it. Before then, I actually declined a team invite.

So, solo queue is a mess. Team queue may be lovely, but I'll apparently never live to play in it.

SOLUTION: Allow for ad-hoc pre-made ranked play. (presumably in its own queue, but still only using solo queue MMR) Restrictions:

• The same restrictions of solo/duo queue would be in place: no cross-tier bronze+gold type teams.
• It would be only a full 5v5 pre-made group matchup.

I think this would be really really good thing for ranked play. I have umpteen people on my friends list, but no-one wants to commit to playing on a ranked team. Yet, almost all of them have PLAYED ranked..... in solo queue. So it isnt that they just dont want to play ranked at all.

Lets give more people more of a chance to play fair ranked games, without having to try to motivate and organize a full time team!
