It sounds like the idea is that you won't get the nuisance mobs of irrelevant quantities of peasants that spawn, block everything, and are a nuisance for everyone. So you will be able to loot for longer, until the resentment builds up enough that a very large group spawns. Not only will the groups be larger, but their stats got buffed so they will actually be able to do some damage. No more suicide charges of 700 peasants killing 1 soldier and wounding 2 more, while 600 of them get slaughtered.
