Still, nobody in chaos goes for a juggerknight start once they pass the 1400s. They all usually go for crawlers and bombers, both of which are almost useless against the spearton. So, provided the chaos user does not expect this start, would it be possible to win against chaos with a surprise spearton
Chaos likes to use fast and cheap units.
The bomber is a good unit for dealing with groups, and the crawler is a weaker but faster and cheaper alternative to the swordwrath. Also the price of the ranged unit (300 gold and 100 mana) and the flying unit (400 gold and 150 mana) means lots of late, experienced chaos players will mass and rush the weak, fast and cheap units.
If the swordwrath didn't cost as much order players would do the same as chaos, and some do still try to mass and rush with mixed results:
Swordwrath mass vs Speartons = Swordwrath win
Swordwrath mass vs 1 Magickill and Speartons = magickill and speartons win.
Swordwrath mass vs juggerknights = juggerknights win
Swordwrath mass vs juggerknights and 1 marrowkai = juggerknights and marrowkai win
Now with Crawlers...
Crawler mass with pack mentality vs speartons = crawlers win
Crawler mass with pack mentality vs 1 magickill and speartons = crawlers win
Crawler mass with pack mentality vs juggerknights = Crawlers win
Crawler mass with pack mentality vs juggerknights and 1 marrowkai = juggerknights and marrowkai win
Crawlers seem to be very effective when upgraded which may be a possible reason but...
Juggerknights are very powerful but cost the same as a spearton so it baffles me why the chaos players don't go for a powerful unit first.
I observed a replay of two high rating (above 2000) players, one order, one chaos and the chaos player used the crawlers as a distraction while the bombers finished the remainders. later after each side had more than eight miners, the chaos player made eclipsors and juggerknights, as a backbone force while the order player used albowtrosses and speartons with 1 giant (Med size) and went on the offensive.
the Chaos player won with 2 juggerknights and 1 eclipsor surviving when the order opponent surrendered just at the end of the battle between the forces.
I think most chaos players just use crawlers and bombers as a defence, as the castle dead is only good against enemies with one health bar and the units are more suited to attack or offence and as it takes time to make juggerknights if the crawlers were any less powerful it would make the chaos player prone to get rushed.
I also noticed chaos is better at attacking and shows this in its units and upgrades Eg Juggerknight charge. while it seems that order is much more defensive as turtleing does not work as well with the chaos units.
Hope i helped :)
