I AGREE, I wish that they would have focused more on developing the main and companion quests and fleshing those out.
Like, there’s so little reaction to the last Durge quest, it really sucks. Good Durge, I was murdered by Bhaal and resurrected in a new body, and my companions are all just like “heh I knew you could do it,” without elaboration! No special cutscene other than Withers pulling deus ex machina on all of us, no camp scene afterwards. Didn’t like it at all.
They definitely need to focus on DEPTH rather than breadth in act 3, moving forward.
