Suggestion:
Increase default "World: Ending enemy level" to 7 at the very least. Perhaps more.
The reason is that 4 seems to be the default, resulting in endgame biters with 300-500 hp and low resistances, while the vanilla game presents biters with around 3000 health. Rampant is supposed to be challenging, no? started a death world with rampant only to find the biters posed no challenge in the end, many many hours in. Playthrough ruined :s Yet they presented as tier 10 with fancy names, leviathan and what not. So I started looking for solutions. The assumption was bug or conflict with another mod, untill I found this setting. I think we can all agree a higher number would be a much more suitable default for a mod such as this.
Seems I posted in the wrong section, feel free to move to suggestions if possible. I dont see any option to do it on my end :)
