I think its clear for any of you min/max RPG vets and D&D vets. Once you know what you're doing its really pathetically easy. Most of the goblin camp dies to a single hit, and thats before we have any huge AOEs.
Stuff needs more HP, more enemy healers, more challenge.
I agree that knowing the game makes a huge impact and once you know the ins and outs combat becomes too easy. But isnt that more of an effect of not having extra difficulty settings at the moment? To me at leadt it seems like the combat is reasonably tuned for someone who isnt a DnD expert, so good stuff like hardcoe and ability to level beyond 4 is comming, just further down the line.
