I find it to be unnecessarily fussy TBH. It's got a load of extra rules around the combat resolution that add absolutely nothing but brain ache to the game. I can see what they're trying to do with the "exploding 6" mechanics on wounds and so on, but it's all just faff as far as I'm concerned. The mixed weapons stuff is micro managing on a whole new scale. And the new base sizes are an annoyance too.
But I like the fact that the armies are all set and the new Arcane Journals just give you new ways to play, not whole new army list power creep.
It's Warhammer though, and I've loved Warhammer for well over 30 years now, so what're you going to do? *shrug*
