Why not take it from a noobs perspective?

I can fill you guys in on that btw ^.^
Sure, it's a pain in the rear to get whooped by someone with a much better strategy then you. HOWEVER, It's a learning experience, you notice what the better players are doing you either figure out a way to counter it or mimic it
As for dead-beating noobers, why stick them all in one spot so it turns into an even bigger problem? Personally I don't want to get into a game, get 3 turns in and then realize i'm the only one ACTUALLY playing. Having maybe just one dead-beater in a game is a little less dramatic.
If you still feel that it's such a horrible thing, why not improvise? Perhaps have OPTIONAL ( keyword here lol ) settings for the lowest rank that can join a game? That way if you don't want to play with the newbies, you don't have to. ( Were not that bad though, are we? )
