This is pretty much a minor request, but I noticed that select Skeleton Key secret bosses have been lacking their cinematic cutscene camera angles centered on the bosses themselves for their encounters every time Wizards find them through the use of Skeleton Keys.
Here's the list of the Skeleton Key bosses that have no camera cutscene angles, by far.
Bunferatu (Upper Halls)
Billy the Cutter (State Wing)
Temple Phantom (Hollow Mountain)
Lambent Fire (Crystal Caves)
Takanobu the Masterless (Cave of Solitude)
Well, that's the list. Hope you can add these in to them someday.
