Spoiler My thoughts : The problem with trading away HBR isn't the enemy building HAs - I'd rather they put their hammers in HAs than in archers or spearmen, both of which cost less and receive considerable defensive bonuses. It's not like 1 star HAs are difficult for a highly promoted gang of Keshiks to deal with. The real problem is if they make construction and have elephants - then your Keshik rush is done. Having said that, they are already done with Feudalism, so I wouldn't worry about it at all - the Keshik rush stops here anyway. Unless you have some absurd numbers advantage, you need seige at this point. Your tech situation is healthy, I'd focus on the economy for now and go for a later push with Cuir or Cavalry to finish it off.
