While I understand your perspective when comparing the game to real life, you must take game balance issues into consideration:
1) Spearmen are currently available way too early (they should require bronze working)
2) They require no resource to build (should require copper or iron)
3) Their primary role in the original game design was to defend against mounted units (however mounted units are virtually non existent early game in the current AND implementation (see below or see my above post))
4) They are anything but useless; In the current implementation, they are build en masse by the AI and myself for early game rushes. In fact I am tired of seeing them cluttering up my early game.
What should happen instead is:
1) spearmen should require bronzeworking with copper or iron to produce
2) mounted units should be more widely available early game (by reducing research costs for mounted techs and increasing the horse resource spawn rate).
Making the aforementioned 2 changes would give back the spearmen the niche which they actually belonged to which was to defend against mounted units. Furthermore it will make for a more interesting ancient era as there will actually be mounted units early game combined with the other units rather then current ******** javelineer + spearmen rushes.
I second that:
Of course spearmen were a good defensive unit against cavalry and lightly armoured infantry. But against trained swordsmen they are not much use.
In the antique world the highly organized macedonian style phalanx was not only outmaneuverd by the Roman legions, the legionaries just simply cut off the spear tips, and cut themselves through the wall spears like a buzzsaw...
In the (late) middle ages, pikemen were in high use, but mainly because of their cost-effectiveness ratio. Later troops (like the Landsknecht Infantery, unlike in civ) armed with heavy swords specialised in cutting down the walls of pikes...
The main purpose of spear infantery was to stop cavalry, which was a very powerful force on the battlefield. But against other meele infantery or archers spearmen just were NOT effective, especcially used defensively.
I will gladly provide sources if necessary.
In conclusion: If the overall value of mounted units increases, spearmen automatically also gain value.
Instead of making spearmen and pikemen stronger defensively (which would be historically very inaccurate) I would strongly reccomend the following changes.
Spearman:
5 strengh
+ 75% vs. mounted units - 25% vs. archers
Pikeman:
7 Strengh
+150% vs. mounted units - 25% vs. archers -10% meele units - 25% vs. gunpowder units
Technology: Military Training!!!
Heavy Pikeman:
11 Strengh
+150% vs. mounted units - 25% vs. archers - 10% meele units - 25% vs. gunpowder units
Apart from the commando bonus it would be extremely important - for reasons of realism - to rebalance mounted units in general, especcially with considerations of terrain.
I would suggest to give all mounted units:
+20% Grassland, Desert, Plains Attack - 20% Forest, Jungle, Marshes Attack. This would be very important. Cavalry had severe limitations in unsuitable terrain and urban combat, but was very hard to beat in the right terrain... there is a reason the horse became the weapon of choice for the peoples of the vast, steppe emires, and not of the city-dwelling peoples or jungle or forest cultures...
+ 25% vs. archers (NOT longbowman or crossbowman) +25% vs light swordman - 25% city attack to represent the effect they had on battle. Formations of unfortified archers or light infantery, in the wrong terrain were simply torn apart by cavalry. This changed when ranged units became more formidable with the invention of the crossbow and/or longbow.
So Affo:
- Please make mounted units stronger/weaker - according terrain
- And consider my suggestions regarding spearmen and pikemen
these suggestions should strongly increase realism and improve the quality of the game
