The game is extremely unbalanced. And if you know about it, and use it to your advantage it also is extremely easy. Like the skill which let's you attack twice…or the enchantment which lets you attack twice. Once you got access to that stuff, which is about when you leave the first area, the game basically becomes expontentially easier until in the end it's just a joke.
That's also the reason why I didn't even bother with the DLC. I basically already played a group of gods. No need for just a sight seeing tour. It was a nice game nevertheless…but the balancing was horrible and a few other mechanics like no xp when being stunned, having a tank class but no tank mechanic and ranged class without working ranged combat were horrible as well.
Edit: If you'd like to check, see a video
here, where I fight some stuff in the very last area. And
here at the position the link points, you can also see all the stuff I had at the end of the game and what route I went. The most overpowered character was the blade dancer. Having two attacks with two daggers, which both attack twice and proc multiple times on ALL enemies (not just the target), everything with a ~50% crit chance was just insane. And one of the weapons also drained mana, which then could be used to attack all enemies at once every now and then…
On on top of that the same character could attack again if she killed one enemy in that turn…a pure killing machine.
At the same time I used a weapon with the barb through the whole game and which he wasn't trained in, just because it had double attack and was still more powerful than a up to date weapon in the trained category.
Oh, and I played without having deaths to make it more interesting…
