I don't really have a problem with Warhammer 2's turn-times, especially after the optimizations CA did with the Empire overhaul back in 2019. Yes, they're still a bit long, but I don't find them to be awful.
What I *do* have a problem with are the game's loading times, especially for battles; they're the single biggest reason why I prefer to auto-resolve combat as much as possible. Loading times are ridiculous, and not just because I currently have a potato for a computer -- they can sometimes take forever even on newer machines.
Don't get me wrong -- Warhammer 2 is fantastic, and I fully applaud what CA has done to bring the world into the Total War franchise. However, the loading times are one reason why I'm not absolutely chomping at the bit for Warhammer 3 (although I'm still looking forward to it), as I fear it will have the same issues, at least/especially at launch.
Also, as far as factions, I enjoyed playing the Tomb Kings and Norsca the most, in the smaller campaigns.
I still gotta try out the Tomb Kings...along with so many other races.
I've spent too much of my time (if such a thing is possible) playing as either the Dwarfs or the Empire to really get around to most of the others yet.
