A welcome change in my opinion. Having played through the biome both solo and duo im happy to see spawn rates reduced a bit. The initial landing is fine as a challenge, but after that it gets very tedious and boring after a while.
There's only so many skeletons you want to parry before you're fed up with the play loop. Hopefully this will make engaging the biome a bit more interesting and better paced.
I might actually mine a spire now...
Nah, the gems in are in the forts, and I get plenty of flamemetal while looking for them.
Put a gem or two in a spire and maybe I'll reconsider.
