Its funny how you are not able to understand how it looks working...
I mean, War defense come from a Base "screenshot", at one moment.
It's easy, so, to manipulate this "screenshot" to give you active Heros in Defense.
War offense come from the normal mode, the Multiplayer side.
As it has been said a lot of time, it's seems to be difficult to offer, during their upgrade sleep,
ability to use Heros in war, and not in Multiplayer game...
In another way, it's also impossible to use spells during Spells factory upgrade, right ?
Same problem...
