It's fantastic for exploration. The whole map is a giant puzzle box.

Just go into it with a sense of adventure. Difficulty is fine, but it's asking you to engage with all the mechanics.

Bosses are also a puzzle, there's basically always a mechanic or questline to make it way easier if you think about all the tools at your disposal.

Don't go into it trying to beeline towards anything, let your curiosity take you, be willing to experiment (not even talking about respeccing) and it's a great time.

If you try to boss rush and get frustrated your preferred style of combat isn't working then you'll get salty

The closest thing to a spoiler I'll give is that they troll you with the map, hard, and you'll constantly end up wayyyyyyy the fuck deep in the shit from the tiny little off the beaten path ruin or cave or hidden wall that you thought would be a 10 minute detour. They subvert the fuck out of that, because you get so used to it from the base game
