Nightmare difficulty is boring and easy.

Enemies are bullet sponges and as long as you spam dodges you can't die, even if you are hurt potions are everywhere and teammates can constantly heal you. Combat looked good and flashy for a few hours than it gets kinda boring. Since I can't turn down the difficulty from nightmare it's gonna be a long grind to finish the game lol.

While the beginning few hours of the game has the enemies rolling over for you on Nightmare, I felt like it definitely gets harder for some encounters. The undead foreman fight was a little difficult for me as an optional encounter at level 14-15. It took like 10 minutes in one try, like my ultimate recharged twice during the encounter, but that difficulty may have come from the fact that I decided to do that at that level as mage before my class really starts to pop off, and without recruiting a warrior yet. Other than that, the Ossury fight to recruit Lucanis felt a little tense.

yes i died of tedium, not the enemy.
