Steadfast and the Horde

A Horde of Black Orcs. Choppiness to spare.

I think the rules for Steadfast and Hordes are two of the most exciting rules to be added in 8^th edition Warhammer. These rules are, in effect, the first time there has ever been a reason to field more than 25-30 models in a single unit. There are exception to this statement – unbreakable models have always benefited from being in as large a unit as you could afford, and the Unit Strength rule did make a small difference (or a big one where Fear was involved) – however for most units, fielding 40 models or more in a single unit was inefficient. The number of models fighting would be much the same as when the unit had only 25 models, and rank bonus would be largely unaffected. Every model dies when the unit breaks and is run down, so why spend the points on the extra 15 models?
