I started another Play-Through of The Witcher: Wild Hunt, Blood and Wine which made me think: Why shouldn't Cities of Sigmar receive a subfaction or models that are more knightly? We have the Demi Gryphs (which really need better poses) and that's it. However if one would combine the old bretonnia style with the Free Guild style and added a sprinkle of fantasy beasts we could have really awesome Toussaint-Like (Witcher Faction) Knights organized in knightly orders or Guard-Battalions, bolstering the forefront of Dawnbringer Crusades, while looking awesome while dong so.
In concrete I am talkin about: Pistoliers on Demi gryphs. Tauralon Lancers (or sth. similar), mounted Greatswords on some weird beast, Dual-Saber riders etc.
Would be really cool imo and not as limited in scope as Bretonnians were, while not requiring its own faction.
