"Weak demons"??

We are talking about the devastating losses that can occur even with a single mistake in a battle against neutral creatures. The demon's troops are fragile, except perhaps for pit lords and devils. Summons practically don't decide anything in the first two weeks. Why? Firstly, they usually move later than the main troops. That is, they don't fulfill one of their main functions – absorbing retaliatory attacks. Secondly, neutral creatures completely ignore the summoned troops and rush straight towards the main forces. And if they manage to do that, the result will be disastrous. And having 30-40 creatures in the first two weeks also seems like too much.
