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!
