I think this is all that's needed. I don't see any negatives.Ok I guess I didn't explain myself well enough:
Buzz, you wouldn't need to play those 50 games because you have an account already. This system would only "hit" smurfs who want to create a new account and play on Medieval Siege.
A legit new player will start off in the New Player Lobby and get rated games since game 1. By the time he climbs his way up to Medieval Siege he will have his 50 1vs1's already, no problem for new players.
