I enjoyed beta 3 quite a lot and I think it is a massive improvement over previous one.
But monsters seem too passive, and it looks like they are afraid of the player Area Of Influence(AOI). I've been plopping outposts around the whole map, and very rarely did something get attacked. Having such passive monsters limits the fun for me, world is not dangerous at all if you can conquer it by plopping outposts.
My idea is that when a monster ends up in the AOI there is a 50% chance that it will become aggravated.
Aggravated monsters become one of the following:
1. Destroyers: They target the source of influence and try to destroy it as soon as it is possible
2. Harassers : They know that they are too weak to destroy the source of influence, but they do their very best to smash all resources in AOI.
If there are no resources in AOI, then they try to find a destroyer and join his group
Monster lairs should also become aggravated and start spawning destroyer monster parties that seriously threaten the source of AOI.
