If they started with the scout instead of the warrior, that would be more interesting.
Although having a strong scout that immediately ignores hills or forests will definitely be a very strong early presence. From looking at the video, it does look like the scout after taking the promo would be at 15XP, though, so that would reduce its effectiveness. I think they really should make a change so that the free promo is free - if my scout can farm barbs easily for the 2nd promo at 15XP, then that would be a lot faster to getting the +20 combat bonus. Although at the very least it will be interested to use them as a Ranger slingshot civ. If you can come with a handful of +20 strength Rangers, they could be a fiersome industrial ranged force.
