With the new WoC army book coming out soon (or for those who bought the spearhead, who have it already) I've been wondering; What should the unit size be for each unit.

I've heard that Warriors are great as a single unit of 12 (or 11 if the hero joins) and Maurder horsemen are a great 5 man harassing unit but other tactics are there when it comes to the amount of models in each unit?
