I can't speak for Minthara fans since I still have not recruited her yet, but I can absolutely talk about Wyll Ravengard.

He's the only companion that doesn't have a proper one-on-one romantic cutscene at the tiefling party. (Even though one does exist from EA and could easily be implemented with minor alterations for the rewrite.) His dialogue and greetings are still bugged. He's the only romanceable character that doesn't have a sex scene. I wouldn't mind the last one so much if it weren't for the fact that this game literally lets you have sex with Halsin as a BEAR. Larian, you have to understand how bad that looks.
