So I've tried several different kinds of military classical rushes after the tech change. One flavor is rushing to C Bows in mathematics and using them with Spearmen. The other is going Iron Working to pick up swords and catapults. Playing on Immortal, imo the c bow plays seem a lot stronger overall. My issue is that against the AI I'm going to have a lot of units to deal with, a c bows handles that a lot more efficiently than swords and catapults do. Further, I think mathematics is a more favorable tech, especially its prereqs like calendar. Lastly, I had several cases where I will go into long sieges, only to have my army hits with knights before I get them. I have found that with some fancy play I can use the c bows to soften them up and find ways to deal with them...but my sword/cat army just gets wrecked by them. Has anyone had better successes with sword/cat on higher difficulties, or do you often use c bows for this era of rushes?
