Not sure if anyone has mention about this, but I think Clan Alliance would be great. As a popular multiplayer-online strategy game, making friends is part of the game now. I suggest each clan can alliance with at least 3-5 other clans. And having an individual chat room for each alliance would be cool. More suggestions are welcome.
This would be cool. However, this is costly for SC. They will be buying new servers. And this would end up into multiple complications. But, this would be awesome.
