My disappointment was immeasurable when I realized on my first run of the story that I couldn't recruit our beloved Loviatar worshiper -- which was a good-aligned one!

Lann Tarv, the Bugbear Merchant in Moonrise Towers, should be someone you can recruit (on a Durge run, at least), and who can join your camp at the end of Act 2. If you prove yourself a worthy warrior, it only makes sense that he would want to join your party to behold the unfolding slaughter of a weak army and it's pathetic leadership.

Sparing the Hag in Act 1 should also have unique consequences in Act 3. Maybe she's willing to barter with you for unique brewing supplies, or she's willing to contract your services to dispatch the hag hunters for an additional augmentation for your Hag Eye.
