if the goth player survive with relatively intact eco to the point where he can spam champions (or other inf) from 10 or more barracks (with perfusion and conscription researched), then 5-6 castles pumping EJW will not be enough to stop the goth player from wining the gameCuz you're gonna boom, mine stone, set up 4 castles, upgrade ejag and then wait for the goth onslaught? Az would have killed goth in early imp or earlier. If the game drags out past early imp where the az has 4 or more castles up and upgraded ejag, chances are the goth is gonna win. Goth don't just have infantry. They have bloodlined hussars, handcannons, skirms with all blacksmith, bcannons and heavy scorp to choose.
But i guess you will enjoy the epic slug out between Riut and Chris where both boomed and did ejags. Chris's massed skirms managed to hold off Riut's ejag for quite sometime. That just shows how weak jags are in aoc.
Who says that the Aztec player will not pump Champions too from his proper Barracks? Aztec Champs are way better than Goth ones, they got +1/2 armor cause of Chain Mail Armor, and +4 attack with Garland Wars. Provided the Aztec has more barracks than the Goth player, it's more than winnable for him.
