This is why I suggested adding an option to turn them off. I don't like them appearing out of thin air to remove dragon infestations. They'll keep themselves in control anyways due to infighting.
I actually like dragons because they'll free up room for empires whose allies are stuck degenerating, and also their only border.
Same, I was talking about the hunters.
Right, I figured that out. Now, I'll sometimes turn hunter interventions back on to "clean up" before welcoming a new monster from a quest result.
