I know what area you're talking about - I had my party sneak around that area and come in through the side. I had made some dialog choices earlier where the rest of the goblin area wasn't hostile to my party.

Also, I forgot about plain old jumping for the first ~15 hours of play. I was so stumped about a route I was supposed to take until I put on my glasses and _really_ scrutinized the action bar.

I gave my rogue an amulet that lets him use Misty Step; it's been an absolute game changer for my rogue stealth archer.
