The game is on "normal" setting. DKS Ego Draconis part

There's a part of the gameplay when I experienced difficulties (about level 10). So I decided to go to the Orobas Fjords and pick level 18 goblins one by one, then went back to the level 11 Black Rings (IIRC I was level 14 or something). Ok, so... life was easy. Then at some point the monster levels catched up. Good, the gameplay became difficult again.

I'm just at level 35 and just finished the flying fortresses. The gameplay became too easy, Raze never even got a chance to go to any of his healing stations. I rarely summon creatures anymore. I stopped drinking potions. I stopped being tactical and went charging into fortresses blindly. So I skipped a lot of quests in the hope that the levels will catch up. Still, the only battle that posed the slightest difficulty was against Zandalor and the Divine one. Even then I didn't have to use any potions.

BTw the game has been dropping Epic(Dark Red) items like crazy starting at level 24. My character has Epic items all over except for 1 ring. I have multiple epic cuirasses. I stopped collecting the set armors since the epic items seem to outclass them. What's the purpose of the set armors if it's outclassed so early in the game?

Is this normal? Does everyone have to go to "options" and raise the difficulty of the game at some point in the future?
