Archaon charging with Swords of Chaos + their ability is great. Massive speed, and much more speed during charge. Archaon's able to immediately go to the target unhindered while the Knights clear way. People rag on the Swords of Chaos but I think they're actually good, they're consistently getting great value, and much more than other Knights. They are however much more of a 'glass cannon' of sorts compared to all other types of Knights. I find they die/get damaged much easier, but deal much more damage. Need more management than even lances.
