Not exactly “every level, but yeah, the way the system is purposely tuned means that your best “Unique†item at level 10 will probably be outclassed by an average “Common†by level 12.
Save for a handful of Unique it’s also worth stressing that every other find is randomly generated and randomly placed, so you can’t make some mental map of your ideal setup but make work for you whatever you’ll find.
In fact having Lucky charm maxed means you’ll constantly trip over “Epic†items opening random containers.
On top of that, merchants’ inventories are refreshed every time you level up or after a certain amount of time.
I said this in the past: I’m not a fan of this type of frantic hunt for better items even in single-character hack’n’slash like Diablo, but whoever decided this system would be a good fit for a party-based game where you have to “refresh†the equipment of a lot of characters was horribly misguided.
Then there’s the very questionable mismatch between a game with a finite number of non-repeatable encounters and items being unreliability random.
