So, I can't seem to get the hang of this. IIRC I couldn't even pull off HA rush on Monarch (with Keshiks no less), though Agg AI was ticked if that makes a difference. How exactly does one go about this tactic? What is an example of a "standard" tech path and what date do you aim to get HBR researched? I've moved up to playing Emperor since the last time I played an HA rush, which is the difficulty I have in mind for trying it now.
