So I am in the courtyard of the Goblin Camp and up in the balcony area where the drunk Goblins are. I attack them, triggering all the outdoor mobs to go hostile. I counted like 20 mobs and my party is just level 3.

1. The AI does not know what to do with you that high up from them. Almost all the melee mobs just stand there, having no idea what to do.
2. I am far enough away from the edge that no ranged mobs can target me so I just focus down the 4 that are up top with me while everyone else just stands around.
3. Once these are cleared, I now just step 10 feet forward to the edge, target a mob, step 10 feet back so I can be attacked. Rise and repeat for each of my players, slowly whittling the pack down.

So, at no point was I in any danger, except from boredom. Larian could have packed that courtyard with 100's of mobs and I would have slowly killed them all and I was just using cantrips and bows.

Game turning into anyone with the high ground wins.
