Battering ram for everyone?

I really like the battering ram for the huns

But I find it kinda funny that no one else can build early siege units. Wouldn't it be cool if everyone could build battering rams? And then the huns would just have a really good one. (and be able to build spearmen too, find it kinda weird they can't do that like everyone else)

Huns battering ram is 10 str vs. cities right? The normal one could be like 5 or 6 str vs. cities.

It would really add some cool flavour and a nice warmonger option in the beginning of the game

Battering rams are meatshields, especially when Great Wall comes into play.

What you want is Keshiks Horse Archers

It's not the combat strength, it's the "+300 city attack". This guy's G&K Israel civ has "sickle warriors" that are basically little spearmen/battering rams that have +200.

Check that out I guess, but I think it's overpowered. If anything it can give you mod ideas. Atilla gets a nifty very early unit, pasture production bonus, and nothing else the rest of the game. That's how the balance is justified.
