Why can't it? It absolutely can – in the form of some kind of buff. For example, a built-in Regeneration.
By the way, the Orc's Special Ability is simply "worthless" because it just adds Fury points, which are also added by cities and Blood Memory. In my old modding experiments, I made Pure Fury a regular perk (naturally, reducing the Fury gain from 500 to 200). And I used General Support as the Special Ability. Which, indeed, looks creepy, especially under Crag.
