I'm at Act 2, and I tried going to the hut by the cliff, but the trapdoor is locked. --- I am Thor Odinson of the Vikings, giant. I am not the god of reason and understanding. I am the god of Thunder and Lightning!
Yes, it's pretty lame that we can't even access the Operator on Iorveth's path. But I did notice that you have much better gear options (Dragonscale Armor for example) and there are more quests so you'll level up faster. By the time I neared the end of chapter 2 I was halfway to level 35.
