Keeping alive Units after battles... with some penalties
I know it is already been suggested and I will delete this if it causes problems.
I know how people wants to keep there troops after battles, and we should keep the troops by paying for their elixer costs. For example - you win the battle and a wizard is left over, and you can decide whether to keep the troops by paying 1500 elixers and keep him.
Again, I know it is already been suggested and I will delete this if it causes problems.
