Idea

Make a friendlist that u can add any player to s friendlist

Create your own character picture

Holiday troops

1. Friendlist: Just use the Facebook link and add people on Facebook, then you will have them in your Friends tab.
2. Not sure what you mean by this.
3. Not needed, if SuperCell would be to design a troop's look, its animations, powers, abilities, stats, etc, I would imagine they want it to stay in the game and not spend that much time only for the duration of a week, which is the holiday events time.

1. Just use GC / FB.
2. A profile pic isn't really needed and would just cause more issues with inappropriate stuff.
3. I agree with devil on this one.
