'.... a Neutral aligned one can lead a human unit, and a evil one can lead an Orc unit.' Inference here, I think, is that (neutral) half orcs could lead a band of raiders or no-gooders! Deffo champion or minor hero for (evil) Orcs. More in keeping with earlier rpg basis of WHFB1e & then 2e character development and story/plot building on the tabletop. On races, again reading between lines (+fan interpretations!) the 'modern' take is that old ones created races to fight chaos. Mistakes made- Elves were too easily manipulated, dwarves too stubborn (but less susceptible to magic/ chaos /base desires but not completely), humans were, well, a failure from the start (similar to first men-susceptible to evil/ morgoth and their greed - in Tolkien's world first age, when they appeared), halflings were not completely corruptible as other interests drove their 'desires'. Ogres were on slab (unfinished, an incomplete project) when the gates collapsed. I like someone's suggestion that ogres were just halflings scaled up.
Also read that in one of the WFRP supplements there was an NPC halfling mage (wannabe Necromancer) that wanted to raise a giant's bones from their veg patch....?!
