Battle mode VS War mode

The idea is simple, an option in your settings where you can select "War mode" or "Battle mode". This would allow a user to pick one of these. With "Battle mode" selected, you will be opted out of clan wars, and you can attack random bases to receive trophy's and loot, like normal. With "War mode" you wouldn't have the option to attack random bases, but they wouldn't be able to attack you, so your trophy's would stay the same, while you could just focus on the occurring clan war.
