Thank you for taking the time to write this up! This is a really good overview of the rough spots in the current version, and it makes for a great addition to my references while I plan updates.
Some of the weirder things you point out (3 weapon slots, non scaling enchantments) are artifacts of system changes that happened before launch. I agree they need to be addressed. They just hadn't made it to the top of the priority list yet.
Thanks!
Since my description may not have been very good, here is the piece of terrain that caused me to softlock. Speaking about the terrain generation, I think it's very cool. Particularly the fact that caves can be generated. It's unfortunate that looking cool is all they're currently good for.
