I'd like to comment on a couple of things I've read
-Numidian Cavalry being weak
-Jaguars being weak
Okay, about the Numidians...the poster pointed out they're weaker vs. archers than normal horse archers and they still die to spears. In my mind the optimal use of HAs or swords is to immediately pillage the enemy's horses/copper/iron so that you face archers. NC can have an easier time choking and pillaging enemy territory because they can handle spears when you consider they get an extra promotion with the stables. As for being on the offence vs. archers, yes they have 1 less strength than normal HAs, but they also have a higher withdraw chance which I believe makes up for it. Therefore, I'd say they are just as good as normal HAs vs. archers and much better vs. melee units and for empire defence.
As for the jaguar, the way I look at him is this - I don't compare him to a sword, I compare him to an axe. Think about it, when you research BW normally you have to send a settler over to a copper source, mine it, and connect it by road to your capital. How long does that take? It probably averages at least the amount of time it takes to get to IW, and I'd even bet it often takes longer. If you beeline for IW you can have jags at around the same time a normal civ would have axes. They don't require any resources and that is what truly makes them shine - you get them out quickly. They obviously have difficulty vs. enemy axes so the point is to run them into enemy territory ASAP and pillage their mines, then they will face archers, or you can simply rush the enemy city closest to a metal mine. So it's not really fair to compare them to swords, but rather compare them to axes. How does Monty's jag compare to an axe, when it's trying to rush a city? It actually compares very favourably. It's str 5.5 and with CR it'll have a 30% city attack bonus, thus it's 10% stronger and has a 10% better attack than an axe, so it can defeat archers much more easily, it also costs less than a sword and doesn't get countered by chariots, and it's a great choking/pillaging unit so in most circumstances it won't have to face more than 1 or two axes anyway. I actually think it's a very solid unit.
