These fights need to be retuned on several levels. Enemies chain-aggro'ing is a very bad look, but there's also just the amount of time the Druid Grove and Goblin Camp fights take. NPCs take forever to calculate their turns and execute their actions. Even playing pretty optimally (I mean, using good abilities and an offensively-oriented party, not setting the fight up in advance with barrels and all that nonsense), these fights can take more than an hour to complete, and most of it is spent watching NPCs take their turn. I've found myself alt-tabbing after each of my characters' turns.
