One, the thread hadn't been bumped for 6 days, it took you about 10 minutes to read it and type your message, and I happened to post in that window? I should have guessed. Also I said thread, not my post. (BTW it is your, not you're.)
Two, I thought you had to kill the sovereign to win, not their city? At least, that is the case in my experience so far.
Three, the two sand golems was a different game, like I stated in my post. And it is no longer early game, but I am still steamrolling the map with them.
Anyway it isn't about destroying factions, it is about a unit that is reasonably common that can destroy everything in the early game with ease. That is overpowered.
