Beastmen may need a ranged unit as you say, but I'm sorry, the Gods did not gift them with that capacity. There are no ranged units in the Beasts of Chaos army book. Making their infantry more capable might be the way to go to balance it out
some.
According to the Empire army book (4th through 7th Edition) the southern Provinces including Wissenland, Nuln, and Averland have been heavily influenced by nearby Tilea and include pike units in their armies. These pikes are typically somewhat smaller, although not much, and are amusingly refered to as "half-pikes". Wissenland has so many of these regiments that they actually outnumber their Imperial-mandated Halberd regiments. Since GW never made the official models you have to mod others for it
But they
are covered in the rules and use the same stats as halberders.
Before anyone suggests more Empire Knights: You don't need to, I think Saladin and I have it well in hand, but I dont think they will be ready by patch 1.4 release if it's gonna be the 2-3 weeks they are talkin about
It's my fault, not Saladin's. He's modeling like gang-busters, but I have too many buns in the oven to keep up with him.
I second Witch Elves for the Druchii!
EDIT: OH! Chaos Trolls actually do look a bit different than Stone Trolls, I dont really think a simple reskin is gonna do it.
