I believe that Clash of Clans is an amazing game. What I would like to see in the future is a better global chat option. I think it should be split into sections more than just random chats and people like "join here" and "free elder".
My idea is that you give your player the option to select a language they would like to talk in which gives them the ability to communicate easier with people. You don't have to specifically be from that country just speak that language and if you speak more than one you have the option to pick whatever you would like.
After that you should give the player to pick what they would like to talk about like certain subjects like clash advice, or recruitment of members, searching for clans, or just a social section to talk about any other subject.
I think that would make global a better experience and more fun to the clash of clans members. I hope my idea helped you and thank you if you ever are able to read this yourselves.
