This seems like a polarizing topic - gonna try to take the middle road. The BATTLES themselves are not too long, but the AI's decision-making logic and animations really take a LONG time. I'm going to go out on a limb and guess that this might be a performance issue and some players might experience quick, snappy gameplay while others have to wait through NPC turns that take as long as (or longer than) PC turns, strangely resembling the worst parts of pen and paper DnD.
