The main problem as I see it is there is a very decently built overland world to explore and very little reason to do so. All sorts of clever nooks & crannies, puzzles, secrets and the vast majority of what is behind them are cosmetic loot with no functional benefit. That is disappointing AF. The flight model is great though and that 3rd Z axis of freedom feels really good. But again, you have great mobility around a well crafted map that doesn't offer much reason to explore it other than simply for the sake of and some minor rewards.
We must pray to a very different god of rng then, my friend, because the majority of what I loot from any cranny, nook, puzzle, secret, etc. is indeed a piece of gear, potion, or money ":D
I get the cosmetic stuff mostly only from completing challenges.
