It's a simple question of which I'm not sure the answer...
When you are upgrading a Hero, why can you simply not use it at its non-upgraded level during Clan Wars? If I was upgrading a dragon it would not prevent me from TRAINING dragons to attack with, I simply train lower level dragons (non-upgraded).
When defences are upgrading they are simply available at the non-upgraded level during Clan Wars.
What is the motivation for taking Heroes 'offline' during upgrade?
