New Idea for next Update

Hello,
When someone attack our village and when we have support army in clan base, ldiers in clan base exit from the castle immediately even if 1 barbar attack the wall. It will be better if we have button to setup army' attack time or my vilages' damage percent. For example; i will change it as send my army in castle at village's damage become 30 percent or 15 second later.....

So, CC triggers at x percent? This would make the CC too powerful, CC is already one of the most powerful defenses in the game, so I don't think this needs a buff.
