Don't queue solo then, queue with others in your gc

In my experience it seems like the queue really hates when you queue as a small group or full group. When I solo queue it pops in like 5 minutes, but anytime I've queued as a group it has taken WAY longer.

Plus queing solo means you can queue "in progress" which always makes it go faster.
