If you go for Iron Working and it turns out there is no Iron (rare maybe 10% of the time?) you can often trade it to the AI. In many games you also want to research IW to clear Jungle.
No. The point is that rushing IW is very very situational. In most cases trading for IW or even teching Construction is the way to go.
so your own speed matters a lot as well.
I always achieved better results with axepult or cannons than with HAs or cuirassiers respectively. Slow and steady wins the race
Comparing HA or Keshiks with Praetorians is simply ridiculous. Not to mention that good HA rush on Deity requires a lot of skill, while even clumsily done Praet rush is fairly efficient. As a rule HA<Keshik<<axepult<<praepult. By symbol << I mean that the left is not just inferior but a rather painful experience compared to the right. It seems that even many of the more experienced players have no idea of the true strength of Praets. No wonder Rome was so underrepresented in HoF.
Anyway, this discussion was supposed to be about Keshik vs HA.
