Well, I’d say yes & no.
I play on the normal setting - which I think is the one just up from easy.
You really have every opportunity (in most cases) to back away from a confrontation as you can mouse over them & see their levels and their strengths. I fight way less than what I see because I just choose a different path. My frustration is that this game is a time-warp enough as it is, and this just adds even more hours. OTOH, I am opening up parts of the map, so it’s not all wasted.
In some cases you don’t have a choice or you are misled - for example, close to driftwood in the 2nd Act, there is a lizard who is about to be hung. I mouse over, the executioner she’s a level 9 (my party is 9) and it’s only her & one other. I engage her and two level 12’s pop out of nowhere. I was pissed off and just save-scummed (I found out later with high enough persuasion you can convince her to just leave and avoid the fight altogether).
+1 level can go either way depending upon their skills and if you can get set up properly for the fight - preferably I get my archer on high ground and my two melee’s separated from each other and I can typically handle it - but if they have some stupid magic like diseased that doesn’t allow me to heal, then it can get dicey.
Overall even though I have my complaints, I’m still playing the heck out of it.
