Request: Allow Heroes to be available for Clan War Attacks during upgrade.
Benefits:
- Clash of Clans is all about balance. Both Heroes are available for Clan War Defense during upgrade, so why not enable them for attacks.
- More clan members will participate in war because both heroes are available for attacks.
- Heroes will be upgraded more often => More DE Spent => More GEMS spent => Win Win for Supercell and Clashers.
