Gotta say, playing N'kai late game and running into a Thorgrim with 8 thunder barges is absolutely insanity.

Seriously, I have no counter, the Dwarves have almost as many armies as me and several have multiple units of Thunderbarges. It's almost impossible to counter, even when I surround the dwarfs with entirely armor piercing units the thunderbarges just wipe me before I can break them and furies melt against thunderbarges.
