We have several larger projects in the pipe, but they take some time, and we're spread pretty thing over them. We have ambitions to work on the areas mentioned -- food, siege, combat, fast travel, the usual suspects -- and we fairly recently did a world reset followed by significant adjustments in at least most of them.
Minor patches to fix minor "random" things is not something we do instead of bigger things.
I don't really disagree with your sense of priorities.
Combat in particular is a big deal, we got burnt a bit on our last rework of it, and haven't had a deluge of good ideas for it, but we are building up for another attack on it.
