I think for units we want more a description of a unit, rather than some one-liner.
Think of the descriptions and stories and vignettes on the FFH units and heroes; that is what we are aiming for. For example:
Bloodletter of Khorne
• Background: "Bloodletters are Lesser Daemons, known variously as the Footsoldiers of Khorne, the Warriors of Blood, the Teeth of Death or the Horned Ones. Carrying blades quenched in the blood of a generation of fallen warriors, they march behind twisted banners that flutter in no earthly breeze accompanied by the chanting of the names of those slain in battle. They are bestial creatures, with snarling fanged mouths, whose skin drips constantly with blood, their matted manes shaped into spines with dried gore. Like the raging god from which they are born, Bloodletters have no desire but to shed blood on the field of battle. They are clad in fragments of armour, which is sometimes melded to their skin, and wield massive swords." (From Mark of Chaos).
• Unit Name: Plaguebearers of Nurgle
• Requirements: Temple of Nurgle, Corruption of Chaos state religion, Gifts of the Plagued One tech.
• Background: "Plaguebearers have distended, cyclopean faces that leer from atop famine-wasted frames and corpulent bellies, split from within by gushing organs. Sometimes known as the Tallymen of Plagues, they count the diseases of the world, numbering the poxes and contagions in sonorous chants that burble and echo from fanhed mouths. Dripping with unnatural excretions, the Maggotkin feel no pain, for they are every lingering death, every moment of delerium and fevered starvation." (From Mark of Chaos).
