One power I think the general should have, is to appoint a new sponsor to an army when the previous sponsor have gone awol (getting paused because of inactivity).
This would save us the hassle of creating an entirely new army to move everyone to when we need to change marshal. Happened a few months back in Sirion (East Continent).
I like this as well. Someone can be paused for months before their account is finally deleted and the army reassigned.
