explains how to use pike and phalanx, perhaps better than I am, although one can extend the logic to mixing/overlapping other types of units.
A clarifying quote from the above:
STW's defense penalty for overlapping units only makes sense in certain circumstances. For instance, I think No-Dachi and Naginata should generally (at least of overlapping them with each other) take a penalty to attack/defense if double-stacked or more, because they need space to swing. Honestly, I always thought they ought to be used in loose formation myself, but that's another issue. Spears and pikes though are *meant* to be crammed together as tight as possible, and later on, with guns amidst them.Battlefield Deployment: Pikemen are the most synergistically-dependent of all available unit classes, and should never be employed alone on the battlefield. Pikes achieve synergy with other, overlapping units of pikemen in double-stacked square formations (refer to my discussion of the Pike Square) or Heavy Infantry (as examined in the Tercio).
If they ever make Renaissance: Total War I can't see how they could do it without allowing what I'm talking about above, and have it accurately simulate the period, unless they do a cheap cop-out of having you recruit pre-formed "pike square" mixed units. Although I realize it's too late for them to implement it in S2TW, towards the end of the Sengoku Jidai warfare actually looked a lot like renaissance europe so it would really be good there.
My suggestions don't really disrupt the basic rock paper scissors thing at all, they just allow you to 1) more easily mix rock and paper or paper and scissors etc for some more tactical options, or rather, to make said options less of a micro headache and 2) allow you more control and options with your rock, paper, scissors; for example, allowing you to order a 4 line formation of spearmen, with the front two facing forward and the back two backward, or alternating lines of swords and pike without having to spin the whole unit around in the case of the former or drag lines out manually for the latter.
I don't know, maybe a formation-heavy tactics would be better suited to a turn-based game, but most people already pause like hell in SP and you've always had to be sharp-eyed and fast of hand in MP already, so I don't really see all the supposed overwhelming complexity.
edit: ...not to mention most of formation doing is done during pre-battle deployment as I've said before.
