Personally I'm very fond of a hero on foot (such as the arch warlock) with crown of command, who buffs 2 x 40 clanrats, and then supported by dual WLC as a basis for any army at least up too 1500 points. I ticks in at 900 points. After that...Whatever you want.
For a 1k list, maybe a warlord for gnash gnaw on their bones?
With the crown of command you typically don't need to spend CP on inspiring presence, so you dont need that many. So the one CP per round would work nicely with a warlord.
So long as the hero with crown of command is alive and within range of the two block of clanrats, the list is surprisingly tanky, can snipe enemy heroes with dual WLC, and guys.... Beware of clanrats in blocks of 30+ buffed with gnash gnaw on their bones! (I prefer rusty blades more reliable in the long run than spears)
