I get it, it's a new game and things need to be worked out. My suggestion is that when either unannounced or extended maintenance occurs to grant a kingdom wide shield (effective time maybe 8 or 12 hours?) to prevent detrimental losses due to death of troops and leader. The pile of troop speedups we get is great and all, but getting zeroed because I am randomly unable to protect my army isn't much fun.
I'm getting used to live under a shield, but not to get attacked just because I don't know when the Maintenance will finish.
