Power creep city
As some have mentioned, the balance in progression is pretty bad. I’d almost feels like an idle RPG in that regard, which is not a kind comparison. And that great gear you found near a boss fight? It’s worthless the second you move to the next area. Nothing you find has any long-term value. The grind gets ridiculous after a while as leveling takes forever, even against monsters that regularly and predictably destroy you while you wander around (and you will wander a lot).
