Would be nice to make some games for newbies only. So the idea is not to allow you to provide a range (3000-5000hrs), but select either lower or upper limits for each of the requirements users can currently enter. Lower by default, of course.
So I might put upper limits at 50 lobbies and 1000 hours, so only newbies can play -- and the lobby leader, like how you can unrestrict individual slots anyway. You'd like to hope in most cases the leader wouldn't pick classes they're great at which can carry teams, so maybe choose medic or something but whatever. The point is, it could help beginners stick with beginners so they don't get overwhelmed in this particular match by gamers with far more experience than them, or straight up amazing DM. Well, depending on the limits. But it's a start.
I suppose it's almost the opposite of ALs but in a positive way. Or rather you could look at it like ALs for beginners, they can be roughly evenly matched too -- not just the AL players.
