This is a simple idea, give us the oportunity to "report" people on queue lines.
There are a lot of "bad queueing beheavor" you can watch on LoL including but limited to: auto-locks, lack of communication with the team (meaning that you won't know what they plan to do with that Olaff), not caring about the fact that someone called that champion/lane about 30 seconds ago, etc.
Bad-queueing is a terribly habbit for a community, and it can ruin a game even before it begins.
One big problem is not only how common these bad beheavors are, but also how likely you are to run into 2 o 3 of these bad-queuers at the same time.
Just icing on the cake, in case you have a REALLY un-communicative queue and want to leave it, the one punished will be no other than YOU! (with a 5-15-etc minutes penalty)
And to make things worst, this ALWAYS goes unpunished. After 35 minutes of playing a match you usually forget that the reason your team is so unbalanced is because Summoner 2 auto-locked Tryndamier. Besides, I believe that bad queue beheavor should be punished with queue related penalties.
For instance, if someone has a lot of "bad-queuer" reports on him, he should have a 30-seconds wait to pick his champion, or giving the rest of his team 20-seconds to "re-queue" in case they see it fit.
This are just a few ideas, the general idea is that bad-queue is a huge issue that should be worked on.
