Mantle design. Depending on weapon, the process of sheating to swap between mantles and general item usage is very awkward/annoying, and ends up in a lot of times with me just ignoring mantles all together, because it's more dangerous to try to sheathe the weapon than dealing with them. At this point the game has a lot of mechanics that falls in under the same general problem. I struggle to come up with suggestions for improvements, probably just streamline it down to fewer options and avoid bloating it too much, focus more on stronger or longer duration mechanics rather than many small things that makes little impact. I understand the design of having to sheathe weapon to heal and sharpen etc, and wouldn't want to remove that.
