Ouch, this is so very worrying because my experience so far is absolutely awesome!
The first area had some brutally difficult fights, and nothing was ever easy (except for a few fights we missed and then had to go back to).
Most impressive of all was the variation the different fights presented, and we've only gotten to one big fight (three levels above us) in the second area, but that again was completely new (with environmental effects and new monster behavior
sandstorm that slowed us all and spiders which actually ran away and tried to keep their distance
).
I mean, I give the battles in the first area and the second area so far an 11/10 score because they were fantastic and really exceeded my expectations.
Here's hoping Larian might patch some new behavior and balancing into the later parts of the game then, before we reach it...
