I would be very happy if you could let the heroes activated during clan war, even when they are being upgraded. Most of the gamers are honestly hard working to bring their heroes to the next lvl, and somehow it seema to be more a punishment, than a reward, coz you can never use them in clan war, which also weakens the whole team. It should be done like with the defenses, which always stay active. Thank you Supercell. Best regards.
