There were several moments during the main quest that honestly felt a little disjointed and made me wonder if I'd actually missed something. Mid-to-late game spoilers follow:
The reveal of Rhena being Syanna felt super brief, Detlaff had his tantrum then buggered off to Tesham Mutna to chill out. He says bring her to me within three days or else. Syanna reunites with her sister who imprisons her. Then three days pass with Regis and Geralt just.. doing what exactly? They know Detlaff went to Tesham Mutna and they know where Syanna is, why not try to convince Anarietta to release her, or try to discuss things with Detlaff? They wait three days, do nothing and the city is attacked just like he said. It felt weird there was no gameplay before the three days was up.
It was also kind of weird to have Regis and Detlaff going off together and then showing up unexpectedly (like at Orianna's house and then at Dun Tynne). It felt unusual for those two characters to have so much off-screen time together. I would've liked to have spent more time with those two characters before everything goes to shit.
The whole Syanna thing felt quite rushed tbh. We hear about her for the first time, then we meet her and she's revealed to be Rhena, then she's imprisoned, then dead. Obviously this would change depending on the ending you choose, but still.
Just venting really.
I thought it was odd that Detlaff attacked Beauclair prematurely. Did three days really go by with Geralt and Regis doing nothing? I thought the timeline was that they stormed the castle, and it was during their subsequent meeting with the Duchess that Detlaff and his vampires attacked without warning
Regis stated that Detlaff was impulsive, headstrong, and easily guided by his emotions. However, he also mentioned that he is not malicious towards humans. I find it odd that he chose to attack Beauclair in order to force Syanna into a meeting. It would've made more sense if he confronted Geralt and Regis instead of taking out his frustration on innocents.
You'll learn more about Syanna's character and life story if you choose to help her instead of seeking the Unseen Elder.
i think that anna henrietta would't let her go. plus, you find out why she's not exactly...easy to get to to bring her to detlaff. detlaff did feel a bit underutilized especially since his fate doesn't change much between the two and when it does it's pretty...bland. as for attacking the city, didn't regis say that while he wouldn't outright attack humans, he generally only did things for those that were kind to him, i.e. that one person who gave him an apple irrc. so it didn't feel too far out there for pissed off angry detlaff to do that. it definitely changed him from somewhat sympathetic anti-hero to "fuck this guy" guy. in the end he was really more a vehicle for the story, not the focus of it, with that being mainly on geralt and regis and anna and syranna
