Not needed. The bronze/silver players in low populated districts can come to silver/gold districts instead of the other way around. There's a good reason for this. As you probably know there's a lot of gold closets running around these days and giving them a free pass to the bronze districts would defenately be a slap in the face of bronze and new players, not to mention the legit silver players.
But it isn't a slap to the face for gold players who generally on Jericho only have 1 district they can play in?
The game is 7 years old. Protecting new players is a bad argument. Protecting "legit" silvers is a joke. Why should you be protected because other players are better than you? Play the game. If people are better than you, get better rather than falling back on "they are a bunch of closet cheaters." I still don't know why bad players need to be protected. Either get better or get thicker skin if you enjoy playing the game.
