Add friends at anytime without connecting to Facebook or GameCenter

If you're someone who doesn't enjoy using GameCenter, or who doesn't have Facebook, it is impossible to have "friends" on clash of clans. Not having friends can be a major problem when it comes to wanting to invite players to clans, or to check out other players levels and how well their base is progressing. I believe adding the ability to add friends would be a great add to Clash of clans but also there would probably have to be a limit to how many friends you can actually have, otherwise some people would just add random people. Along with the ability to add friends there should probably be a 'Search for friends' tool that way navigating in order to add people you know is much much easier. Again, this is a just an idea and is love to see what else you could add or tweak to this idea.

When you have friends stored on Gamecenter's servers, it's better for Supercell than if you have 50 friends, all stored on Supercell's servers.
