Just some early thoughts
1. I really liked how Bangar, an incredibly charismatic(at least for a Charr) leader got his own voices taken away, just to become the voice on an even more manipulative being. Its a fitting irony for him.
2. Similarly, Smodur getting unceremoniously killed in a sniper attack by Ryland was equally fitting for his character. He is defiantly one who didn't deserve to have a heroic death after what he did.
3. I liked the expansion of the lore of the Drizzlewood area, the settlement there originally being tied to Olafson from GW1, and some details on early Human/Norn diplomatic relations was good.
4. The revelation that Owl is still alive, and that it has been brought back, opens up some interesting possibilities in future episodes that I am interested to see.Nice to see Anet didn't just go with the rather boring "its dead Jim" answer that the game has suggested was true.
5. In some ways I am glad that Ryland wasn't just a tool for Bangar. There had been some hints he wasn't really committed to Bangar for awhile now, and NPC conversation in the first half of Drizzlewood suggested he had larger plans. Him becoming the champion of Jormag over Bangar is an unexpected, but more interesting, turn.
