My clan is very good when it comes to clan wars. But there are times when war isn't going according to plan. So what I think would be a useful tool, to put are selfs out of misery is a forfeit button. Now I don't know how it would work but I would say it would be the same as losing a war. The clan that forfeits will only get some amount of loot rather that all of it.
I don't know what do you guys think. :)
