I'm trying to catch up with this disastrous thread, so let me just link how I think the queues should be structured:

Here's some logic..
1) Solo player - You don't have friends on or your situation limits the want/need to play in groups.
Remember that most tourneys are run in the solo queue, so this becomes an issue.
2) Small group (2 to 4 players) - You only wish to play with your friends, and have a good time. You're not large enough to be a clan/group/unit, and just wish to play together, regardless of result. Of course, this also occurs when not enough of your group/clan/unit or friends are not on yet.
3) Large group (5 to 12 players) - You're probably in a clan/group/unit wanting to just win games... bleeding into competitive or at least semi-competitive. It's probably the closest thing you can get to practicing before CW or whatever turns up (league play or whatnot). You could have quite a bit of friends... that are invested in this game. This is where you're at.
While, some players will bleed into multiple sections (like casual players in bigger groups), it is incumbent upon the biggest premade (usually 6-man or bigger... being 50%+ of the group) to actually play competitively due to having the MOST CONTROL over the outcome of the battle. IMO, once you effectively grow the group to a certain size, it is the responsibility of the biggest premade to want to win, instead of just being casual. It's not "casual" anymore when you've reached that size.
In my proposed structure (listed in the link), it addresses the 2-4 man which I consider "casuals" that need to isolate themselves from the big groups. The "competitive" queue will have a more flexible MM structure (so, imbalances will naturally happen, but if you're a good player/group, you shouldn't be whining about it) while they are provided bonus C-bills for participation... separating those that don't know how to "R" vs those that will dish out an arty because their group demands it.
I hope people understand that with the current system, I certainly understand how the system is flawed for smaller groups, and I believe my suggestion addresses this particular nuance, while making the competitive queue "more realistic" to what CW match construction may be most similar to.
I wish my message wouldn't get lost in this shuffle..
