There are plenty of people Perdan could fight, and plenty of reasons to do so. The slow recovery speed isn't what's stopping them.
For Nivemus, yes. It is one of the reasons why they are not going into war. Dunnera will most likely be stay away from fighting anything until next July until Dunnera take Krimml and wait for the city to recover.
Also, BT will be very slow for until realms recover too.
