I have complaints about Moder but it's really just complaints about the mountain biome layout. Our Moder shrine is on a small ledge surrounded by steep terrain in every direction. He takes minutes to land, and when he does it's on a rocky ledge and he just sits there awkwardly thinking about what to do while we shoot him. 90% of the fight is him struggling to path around, he rarely attacks.

In general the mountain biomes feel too constrained, they are smaller on the map compared to other biomes yet need to reach a certain height to even spawn in useful things.
