Doesn't mean much in the context of this thread since camel archers are available, but basic infantry is not completely useless. It is just that if you go that route, you need to place a focused effort on it to make it work. Discipline + Heroic Epic + Great General = ~50% increased combat strength before promotions are even considered. A 14 combat swordsman becomes 21, a pseudo-longsword. A 34 rifle becomes the equivalent of a 50 great war infantry. Throw on the cover promotion and camp outside of an enemy city with ease.
With enough focus and strategically moving through the tech tree, you can even attack cities themselves with little damage in return.
This isn't meant to imply that you can ignore range; crossbows/trebs will always be useful, just that basic infantry can greatly enhance the power of your military. Keep them fortified down on key tiles to soak up enemy hits and protect your ranged. If an enemy ranged unit wanders too close, one-shot kill. Purposely send them in range of cities partially damaged to draw fire away from your ranged units.
All this said, 2-3 infantry per group of ranged units is enough. If one dies rush buy another from your heroic epic city. I also try and keep a siege unit or two in the mix, as while crossbows ~> gatling loses range, cannon ~> artillery gains range. A heavily promoted artillery is ridiculously good, and if the game lasts long enough until rocket artillery, it will drop cities faster than a handful of stealth bombers. Worth the investment.
