Use of upgrading items in clan wars

We frequently have clan members have to sit out a war because they have a hero upgrading, or more commonly, their spell factory is upgrading.

It would be nice if those things could be still available at their un-upgraded level for war attacks. There is precedent for this on the defensive side as a defensive unit that is even in the initial build is already available in the war, even though it's not available in regular activities.

The spell factory is problematic because you would have to somehow limit spells made during this time to war attack only but that seems like something the devs at SuperCell would be smart enough to overcome, right? :cool:
