I've been a long time protectorate player but recently started forraying into Hordes and have a small contingent of Trolls, I have a couple of casters (pMadrak, and eDoomy) and all of the beasts I'm interested in, minus the storm troll when it comes out, but now I'm thinking about Units. I'm looking at the Champs, and Scouts. I also briefly considered the runeshapers, but pretty much because I already have Janissa. Any advice for a new troll player on where to start? I'm thinking about two units total, as I'm not trying to have it spin out of control like my Menoth habit.
