Or what I didn't understand when I started my first campaign and really should have taken the time to understand.
There is one other thing you must learn to competently play Total War: Warhammer. You must learn all the command key controls because trying to do it all with a mouse is an exercise in frustration. So, to assist me with doing that I created a keyboard command picture I can keep up on my second monitor while I play. I make it available to those of you who read my blog. Please share it freely.
