Sneak Peak #3 Clan War Opt In/Out February Update 2015
February 2015 Update Sneak PeakClash of Clans just released the 3-rd sneak peak today. After two previous sneak peaks Custom Clan Badges and Cannon level 13 we have now the option to get or remove yourself from clan war. So if you aren't active for the week that you can Opt Out yourself and you won't be in the clan war.
This is a lifesaving feature because now you don't have to suffer or kick someone who is not active, they can just remove them self's from clan war and that's it.
Here is a video from Chief Pat that explains more about this feature :
