I like this. It's the way I originally intended them to be, to emphasize that these mercs primarily lived outside the Kushite heartland. I'm not qualified to comment on how this affects balance though, although it seems similar enough to the Roman military camp.

So, personally, I kind of agree with Mimo on this:

@Hannibal_Barca , sorry, to clarify, I'm fine with no techs for mercs...

@Hannibal_Barca The reason behind the Blemmye camel merc is that Blemmye formed the Eastern section of Kush (the Eastern desert people, Beja). Without them, there would be no Blemmye at all, which would make the Kushites feel a little less like Kush... Civ unit rosters need to be based on historically relevant military units as far as I understand. It doesn't matter that there are similar types of units. If they're "useless", people won't use them (much) in MP (which makes it a non-issue to begin with IMO), and most people enjoy SP, and the choice of a historically accurate variety of units regardless of their exact stats...
