Well, its ongoing, but there are two things I noticed.
- Early on in NG+, human opponents are very difficult as in they deal a lot of damage with one hit. Nothing I can't fix by playing better.
- Now that I pick up more expensive gear, I have difficulty selling them because shop owners carry the similar kind of money as before NG+. They definitely need to carry more gold so that I don't have to fast travel 10 times to sell all the unwanted stuff. But even if I could sell all the unwanted gear, I'd have so much money that I'd not have anything in the game to spend them on. So, I think CDPR should fix this by 1) Giving more gold to shopkeepers and 2) Reducing the number of weapon drops from enemies.
Another workaround could be to give the armorers more cash than before and have them carry more rare crafting resources than before which are needed for those school gear so that I can use all the cash I make from selling the more expensive gear somewhat reducing the need to loot everything in sight.
I don't mind looting, but still think I need to do too much of it. This is the thing I like least about Witcher 3. Mass Effect seems the best RPG in that respect.
