Of course, it may be possible to trade with the AI if they have spare iron (I'm not sure how often this is the case early game, but it might happen), use this iron to war on another civ for their iron, and then let the agreement end naturally (unless you still want more iron for more units), and now you have your own iron.
That's what I was going to say. Trade for 2 iron, build 2 catapults, and take an enemy city with iron. Ironless starts aren't bad, but they do require actually talking to and trading with the AI.
I'm not sure if horses are completely useless. Sure they can't take cities any more which is a huge nerf but horsemen may still have their uses like killing enemy units before you reach the city. I don't know how much their strength got lowered but even at 10 strength I would probably still use them. Hopefully we will see something like a combined arms strategy as a viable choice.
Yeah, I like using Horses to take out siege units, and I think that's still a good use of them. In addition, attacking swordsmen (especially weakened swordsmen) and then retreating into the city will be a smart move.
Anything that gives Rome a boost is a good thing, imo
