While I do like Spartan's idea, atm I'm using Brujah's mod. Found it a good way to represent the lore, and as far as I could tell in battles they did nicely, although dying off if used against hard opponents. Most of the time I would have like 10% of the unit left, which would be awesome if they would turn into Troll/Dragon Slayers (Cataph made a nice unit), which I would disband or merge, and then recruited new. Pretty lore accurate if you ask me, while still having value in TW. And with his mod, Ungrim's slayer army works nicely (especially with some extra slayers like Cataph's, or Long Drong's by Dodgy).
