I can't disagree with you in that. Tier 1 unit hordes are a really yummy wave for every monarch! Liches, Weather Witches, Fire Mages, Acolytes of Anu, Mind Mages, Fallen Angels, Neo Dragons and holy dragons also find those Goblins a delicious target for their spread area attacks! However, tier 1 hordes are not funny at all if you don't have area attacks ready to strike them. Anyway, yes I was playing against AI. If my opponent was human, he/she would have expanded much more than this.
