Howdy, I also posted in the legion forum (my first and true love) but that's not to say that I don't enjoy a little troll fun now and again. I started buying trolls for the same reason I got legion, I like the models (though for a different aesthetic). Eventually I will get around to painting them, but for now they are all assembled and ready to play in some friendly learning type games.
I am going to be getting back into it with some buddies who will be playing Khador and Protectorate and am looking for advice with some 25 and 35 point troll lists. I am limited to just the models I have at the moment. I am less interested in optimized beat down and more in fun to play and competitive.
