I have read in some threads and in one of the news updates on the main site about a limit how many heroes and artillery you can field in relation to your other forces, but couldn't see anything to that effect in the rules. Did I miss something or is that an outdated rule?
That was a table in the last edition, or at least was with the non-skirmish versions of the game, with which I'm more familiar. I am happy it is gone. There was some debate recently about relative value of troops and monsters/vehicles, but I like to see flexibility in army building.
If I have character models for my army, I don't want limits telling me I can't use them.
