Since I picked it back up, I've only faced opponents that play Beasts of Chaos, Hordes of Chaos, Dwarved, and Dark Elves. I've played some mock battles with Orcs & Goblins, Brets, Wood Elves, and VC.
I've yet to face TK, Skaven, Lizards, High Elves, or any of the fringe armies, and doubt I will. My local shop is pushing to get a league together, but the sad fact is I'm the main customer for most models. The others playing are doing Empire, Wood Elves, and Dwarves. So it makes for a unique blend.
