Zero training time for war troops
To help make wars more competitive and more FUN, my suggestion, is to make your War Base an "active" base in the sense that you can still interact with your buildings. You would be able to train troops, and create spells. In your War Base, all troops you create do not require any training time, and are created instantly - but you still incur the cost of training those troops. To an enemy clan member scouting your base, the troops would be hidden, so that they can't see the troops you are training. The kicker to this idea, is that war troops can NOT be used by your farming village. This results in two things:
1. Instant War Troops.
2. The ability to train farming troops, while having a war army ready to attack in war.
3. An easier time organizing attacks, since troops can be ready quickly.
4. Higher consumption of resources (elixer, gold, dark elixer), which I'm sure Super Cell wouldn't mind ;)
The same would apply to the spell factory, in terms of creating spells.
Our clan has tried several things to try to organize attacks, including the use of clashcaller.com. The goal is to get lower ranking members to attack early, so that higher ranking members can clean up bases that were not 3-starred.
Because of time-zone differences, and just personal life situations that take up time, it's been very difficult to get everyone to attack at the ideal times. This idea would go a long way to making wars more fun and easy to organize for everyone!
