niffweed17 said:camel archers, on the other hand, have even less of a discernible bonus; they have a 25% chance of fleeing combat, whoopee. beyond that, they only have going for them that they dont require horses. that would be nice if it were a replacement for horse archers (or even chariots), but for knights horses are generally already a valuable commodity: otherwise, you're liable to be dead.
To be fair, my impression has always been that UU's are designed to put a small advantage over the unit they replace, although a couple of them are overpowered. The 25% withdrawal chance means that if you have several camel archers stacked and facing a force of similar strength, the odds are tipped in your favour for an attack spread over a couple of turns and so can eg. make the difference in whether you take a city. The not needing horses (I think it's actually horse AND iron you lose the need for) can mean you don't waste valuable units guarding your resources. And of course, if you're unlucky enough not to have horses... (On one occasion I expanded as far as I could. No horses. So I moved in on my neighbours the French and decimated them. Stillno horses anywhere in sight. It does happen...)
