The response that it's too hard has been weird to me. I'm not very good at these sorts of games but it hasn't been terribly tricky compared to other parts of the base game. And I'm having a lot of fun with it.
I do think the advice of taking advantage of the balancing mechanics they literally put in the DLC to make it challenging and help mitigate that is solid.
I wanna say this is a possible symptom of people who beat the game ages ago, put it down for a year or so, returned for the DLC completely not warmed up, and then perceiving it as insane difficulty off the bat
Im actually surprised that I have liked it as much as I have. Im a horrible gamer when it comes to reaction time and man I hate the platforming. Once I got used to accepting dieing, running around to grab stuff and not worrrying about surviving after, and search cheese X on youtube its been fun. Sorta heat attack, stressing fun. Fun I sometimes want to avoid :)
The scadutree buffs are pretty big from what I can tell, I've got a bunch becauae I explore a lot on first runs and it seems to be at least 3-4% boost to attack and defenses, with some of the new talismans too found there's a lot of stuff to work with.
So far, feels pretty well balanced, it has challenge but I've not encountered anything that made me question how I died, first few big fights were pretty well telegraphed and super enjoyable. What I really like is that you can go try something else if you hit a wall, go level up a bit, try new gear or different approaches
Knowing how the vocal minority thinks, they're probably deliberately ignoring the advice because they think any form of preparation or mitigation is cheating.
