Close game. UD tried to capitalize on war of attrition by constantly killing peasants and hoping to keep HU's army small. Fortitude wasn't going to play that game and amassed knights on the side, which allowed him to counter UD's army. The experience from peasants had diminishing returns as HU was able to catch up on experience with its superior army and staff. It's hard to see what eer0 could've done better.
he just shouldn't go tier 3 no? if memory serves tier 2 fiends was most often used strategy in this MU before 1.30. You either go mass fiends or rush destros, but not both.
If I'm not mistaken he had knights/copters, so burrow would just feed experience as copters see invisible. He just got outscaled & lost to the expansion.
