Trogs, really? I was sure that you had written Tyrants because I find it rare that Trogs excite me. They aren't good enough on offense or defense to be anything more than OK line units, holding on long enough to let your good units get to work.
In a tournament situation, where you're building one army to take on all opponents on an empty billiard table, I agree with you.
Start throwing in terrain using the optional line-of-sight restriction rules from the Advanced Rules, and let the Lizardmen player know which faction he's going to be playing in a given scenario, so that he knows he's facing the Undead or the Umenzi (for example), and I think you'll find that masses of inexpensive Trog Spearmen can be very sexy.
Cool. Generally I love fighting Trogs, even as the Umenzi...although that could be because I've "Chosen" some units that are hard for a 5/5 to get into the yellow.
The Undead are absolutely another matter. We do try to minimize the rocks-paper-scissors of Battleground, but the Undead definitely have a 'cousin' in the Lizardmen.
