I haven't yet got around to playing it, been waiting for patches
I'd wait some more in your shoes. The patch to hit next (Raze will hopefully correct me if i'm mistaken) brings some very necessary changes to balance and gameplay, including a harder mode.
Depending on what kind of build you may end up with, game as is now may disappoint you in terms of challenge/difficulty/pacing. For example, assuming you fancy running it with casters, you will find it ridiculously easy, even when lacking any companions
