Give an Ancient a Murder of Spites and an Annoyance of Netlings. Watch Bloodthirsters (And even more so Blood Dragons, who have issue challenges) cower in fear.
Answered your question on what Ancients are good for? (The thing is, all Lords are good. Highborns enable you to create all-elven armies by movinG EG to Core, can be made into very nasty Alter/Wardancer Highborns. Spellweavers have the Wand and Lore of Life as their main selling points, while you will have serious trouble finding a better duellist than a kitted-out Ancient)
