Hello im loudpack513 and im here to present the idea of being able to use your heros for war even though their upgrading. Im currently a co-leader is a war clan called Medieval Legion and we war 3 times a week, i find it very painful to lose your heros for war when upgrading. Im suggesting that tou can create a way to use your heros for war at the previous level while their upgrading because lets be honest no matter how close u make a match if u cant attack across the board on war its hard to win and being down 1 or 2 heros puts you at a huge disadvantage and i would like you to consider this idea. thank you for your time.
