NOTE: Don't close out of this thread yet, I am not saying preparation day needs to be shortened.

Clan wars are a great aspect when playing Clash of Clans, however I feel as if preparation day tends to drag on. If you are like my clan, you usually fill war CC's in about 2-3 hours. So what is the point of a 24 hour preparation day?

Obviously you can't decrease the time, because that might become an issue. I'm not saying Supercell needs to decrease preparation day to 12 hours, or 6 hours. The idea I am proposing is something that has to be approved by both clans in a war. It could be a button that says 'Ready For War!" that notifies the other clan that you are done and ready to proceed with the war, and the other clan, if ready, can also hit the button. Starting the war.

Let's say "Clan 1" is in a war with "Clan 2".
Clan 1 is finished with war CC donations in the first hour or two. The leader decides to start war early.
Clan 2 finishes in the first 3 hours. They now decide to hit the button, and start early.
And now it will continue into the normal 24 hour clan war.

Remember, I am not an expert so let me know if this is unusual or wouldn't be a very good feature
