This has been a huge problem for me and many others in wars and farming. We really need our heroes to be able to fight when they are upgrading. I have thought of 3 ways this can be done.
1. Heroes able to be upgraded in lab.
2. Heroes recovery time affects upgrade- if hero is damaged for 30 min worth that much time will be added to the upgrade ( max time upgrade takes is 14 days but ex given is still the same)
3. War heroes - heroes are only allowed to be used in war when upgrading
If this could be done it would be a huge help to those upgrading heroes
