This would be a great feature. How it works:
You can join up to 5 different clans at once. You switch between by pressing the chat button and there will be 6 different slots (1 for global)
You get to be in the full clan, solving hopper issues by being able to be in 5 clans I.e you have family in one clan and want to stay in your war clan.
Like this? Join my clan Colbalt Legends. Brand new and have 8 current members.
Personally I don't like the idea (no offense) because then one person could participate in 5 different wars at one time and supercell would have to make major upgrades to the clan castle. Also do you really want to have to keep up with 5 different clans? Besides. There is a thing called loyalty to your clan you know. Can't do that if your in multiple clans.
