And frankly, blood micro is annoying but doesn't really take very long. Even with a lot of hunting provinces, it's only a few minutes of clicking every turn.

The real time hogs for me are more fundamental to the complexity of the game. Scripting for large battles. Setting up boosters, protection and gems for dozens of mages. Then changing it all next turn, when I've researched a new level.
Equipping 5-6 thugs/SCs a turn and forging gear for next turns set. Especially when they all have different needs due to different paths and/or enemies.
Running out of room in the lab, so all the gear for the above has to be offloaded onto other characters and then searched through when I need something.

That's where the hours go in my lategame turns.
