See the great thing about this game is that even if you don't like a feature it will eventually get reworked.
New drinking system seems ass in theory but we will see how it plays out, but I don't have high hopes for it. Eating in this game already feels like a chore due to the ungodly amounts of food you have to eat/keep eating in a single day. Drinking less so. If I had to guess, finding water is going to be either really easy that makes the dew collector pointless, hard to find to where it's absolutely needed, or like how food is where it's common but you have to eat a whole stack of canned goods to sustain yourself for a single day. This reminds me that I need to mod the rates that the food/drink bar drain the next time I play.
Now correct me if I am wrong, but it sounds as if trading is tied to your level correct? That sounds awful. I like the option to buy something good if you save for it or know a good way to make money, which in my opinion is fine. The way it is now, buying good stuff is slow but a good chunk of that is because of the cap the traders give due to your level with them (or was that tied to gamestage? Either way). Make getting money hard but not too hard with a nice and balanced economy (easier said then done really). See that level 5 shotgun you've been eyeing? Yeah that will cost 5000 dukes but if you loot for five days straight and with a bit of luck, you can have it. New Vegas did this alright despite the prices for certain things being absurd. I personally don't like artificial caps to certain things.
