Personally I think that they had intended to make the Gortash segment more about political intrigue. Compared to Orin and Ketheric, Gortash leaves so much evidence talking about targeting specific patriars and his strategies. One of the easier ways to get into Wyrm's Rock funnels you into the easiest area to access the rooftop lair of Gortash too. The existing quests tied in with Gortash involve weakening his bargaining positions (newspaper and the Gondians), so it feels like to me that we were supposed to be able to expose Gortash/helping the patriars to prevent him from becoming Archduke.
Additionally, it is odd that the Stone Lord is associated with the Bhaalists when the Zhentarim are a Banite faction, but that whole segment felt undercooked.
