My most damaging wars were conducted against the greeks with an early warrior worker grab followed up by Axemen offense to pillage his copper/iron resources and wrest control of 2 Greek cities, namely Sparta on the hill near the silk and Corinth on the coast next to Athens, stealing his Iron Supply with a culture bomb. Due to this Praetorians were never needed, if you beeline to horses you can lay on so much more devastation in much shorter time with Chariots, to the point that Horse Archers will solely be fighting Archers which is a decent match up for you (the best part of this is it works for ANY civ)...they're not overpowering and you will suffer losses, but when you can control an enemy civ to this point Praets are icing on the cake not the means to the objective. I'd rather be in a position, to use Praets as a superior decoration than as a needed piece in my war arsenal, especially in this game due to the greek Phalanx. I saw many people were assaulted at their Iron supply, some lost it whereas others defended well, my point is: relying on any UU to overpower your neighbor is not always going to be an option. The key to this war was never being in a position where Alex could pose a threat on any level, but to keep him expanding in your direction so you could focus on other objectives (like infrastructure) rather than building settlers. In all Alex managed to build 3 Axemen, 3 Phalanxes and 1 Swordsman in my game, I didn't destory him until 1100ADish...everything else was archers and warriors. Making my wars with him much easier to control and suffering light casualties with some very well promoted troops.
