Yeah, I'm with Katitof there.
The best loot should never have been craftable I reckon, and it's one of the highlights of A18, that Tier6 can no longer be crafted.
Farming is in a better state than it's ever been I reckon, at least, as I've experienced it so far in my single player game. It's no longer a matter of days before a farm has you overflowing with food.
Repairing is also in a much better state, and I would not at all agree with the idea of only being able to repair what you could craft, because again, I don't think you ever should be able to craft the best.
So, what would I change? Well, so far I've noticed (on a sample size of just one game), that loot is somewhat too easy to come by, ore veins are a bit too easy to find, and pay out ore quite a bit too easily.
I spent 1 game day mining Shale in a nearby desert (which I had no trouble at all finding), and brought back what turned out to just off 70,000 gas cans worth of Shale Oil for my Chemistry Station. As a single player, I expect it will take a verrrrrryyyy long time to use up that supply. That said, I also don't mind if they don't adjust that either, since I'm not much into mining anyway.
