Battle day gets boring when you are done with both your attacks. Allow players to attack all war bases - only once each base. Only the bases that have already been attacked. Don't count stars, destruction towards war score and personal profile. Just let the players attack bases like any other multiplayer battle except you don't get any trophies.
Added benefits:
- War practice
- You get the available loot for each attack
- Share attack replays with clan to demonstrate strategy
- Don't have to spend search money to find an equal base to attack
- Can even allow war spectators to do this
To reduce the risk of exposing any more traps on bases that have been attacked but not yet 3-starred, only allow dummy attacks on 3-starred bases.
