It's a bummer. I'm still doing OK with them, but last night before a game I was doing my usual, "I think Empire is a solid middle tier army," bit when my buddy was like, "If Empire is middle tier, then who is below them?".
It was a pretty obvious question, but I hadn't thought about that comparison that way before.
I realized that I had been thinking more about relative match ups, than absolute performance. For example, I find Warriors of Chaos to be a pretty easy match up for Empire, so I had been thinking of them as worse. I think we also do pretty well against Orcs and Goblins. But that's not the same as outperforming those armies overall.
I'm still pretty happy with Empire. But I have to admit, I can't name an army that's worse than us.
