As already said I am a complete newbie to RPG. After my first round of mistakes in my first playthrough yes - I find it a bit easy. Example - I ran into the 7 character level 7 wolves group Cyseal southeast by accident with a level 5 party. No dog support - was on the far other end.
It was a ridiculously easy fight, although I could not prevent a gang up one of my party members which died. This 2 levels below, outnumbered and surprised (no battle preparation work possible).
Yes, on hard.
