I think the combat is difficult but not impossible. I've played it with my first 2 rolls being fighter, 3rd being a warlock. I always grab all the companions except wyl and then I do the ruins first. By the time I get to druid grove I'm level 2 already. When I get to the blighted town, I usually get close to if not level 3 by that time. I haven't gone past the goblin camp temple yet and the hardest fight I had to do was right outside the goblin camp where if you don't kill that one goblin near the back of the small camp he hits the drums and calls a bunch of gobs in. I had a really difficult time there but I won by funneling them onto the bridge and throwing grenades basically cause they did way more damage than my ranged attacks and I didn't want to take a chance missing melee swings. My take is that its not impossible on classic, def challenging, and playing with friends we usually win every battle but just requires a lot of strategy. I rather like it myself. Just my take.
