You aren't rebutting anyone, you're posting noise.
I'm making a contribution to the discussion as someone who really, really wants some form of advanced lobby to come to fruition. I don't care if you think it's noise, because I think your suggestion (which we're talking about below) is crap.
tf2pickup tell new players to go elsewhere, there are no newbie mixes atm, and normal unadvanced lobbies are horrible for medics, even in Mumble lobbies.
Maybe you could host 2 per day and save European highlander. Look, the highlander medics currently playing learnt okay, I'm getting the impression that part of your reasoning leverages on taking responsibility for ensuring TF2C increases the number of medic mains. I think you're way off base.
So, what you have to do is give them special privileges. First, lessen the entry requirements - no league history required. You'd be looking to find new medics like REM, he's a great recent example, although it usually takes them longer to get a team so they can keep mixing for a couple of months. Let them pick another player on the team, as tf2pickup do. Give them a different colour in the online player list so they feel like bosses. If advanced lobbies are normally scheduled, let them create unscheduled lobbies (but they can only fill the medic slot). Stuff like that.
I don't think it's appropriate, or particularly relevant, to give an example of one guy who you say is a good medic and point to this player as a represention of all the good medics we'll miss out on if we don't allow absolute newbies to play medics in 'advanced lobbies'. Again, I feel the need to remind you that medic is arguably the most important (or certainly top 3) player in a game, and allowing absolute beginners to play this class can, and most likely will, reduce the quality of 'advanced lobbies' more in line with regular, current, yolo-esque lobbies.
In fact, I'd sooner vote that we only allow people with 1500 hours in the game play medic in advanced lobbies, than vote that absolute beginners should be allowed. The only real reason you have put forward to allow beginner medics to play is that, otherwise, we will be force to wait ages on them starting. You have shown no evidence to support this view, however, so it stands alone as an assertion at the moment. I think we only need to take a glance at tf2pickup to see that what you are saying is incorrect.
I do, however, agree that if you sign up for a class and not as part of a particular team, medics should get the choice to choose a player to be on a team with to make it more appealing or certainly not much less appealing than playing in a regular lobby which is open to stacking.
