As far as i know the only puzzle in EA is the one in Goblin camp? And that can be bypassed by discovering a lock just little to the side and unlocking the doors by that.
So, if Larian keep this style and allow us another way over puzzle ... i doubt they can really bother anyone.
I still dont understand why cant we change Race for our hirelings. Lets us play Githyanki as racist as they trully are!
