While that firstly does not really answer my question
I would have to point out that foot knights and even swordsman in some situations are better at that job while being having less of an impact army strength wise.
I find the comparisons to building an army list in the many table top games like Games Workshop having exactly the same issue.
"Sure you could take mounted knights, but for the same army strength cost you could take x swordsman"
Actually I'm gonna go check the army strength cost of every level 5 unit in the human army and post back, check my figures.
*FIGURES* Ok heres what I got, which was fairly interesting
Swordsmen - 18
Macemen - 10
Halberdier - 17
Cavalier - 15
Mounted Knight - 15
Foot Knight - 12(!)
Crossbow - 12
Archer - 11
Peasant - 2
Cart - 1
Fire Cart - 3
Palisade - 0
Trebuchet - 2
Seige Tower - 0
Battering Ram - 1
Annoyingly though there seems to be once again more hidden data in this regard as despite carts seeming to be 1 a pop I have a group of 60 on the world map as transport with an army strength of 80. I'm assuming resource on the army may
factor into this as otherwise it has to be some weird algorithm where by a greater number of units exponentially increases the army strength.
Looking at the figures though I am wrong in my assumption of mounted knights being to expensive compared to cavaliers, they have a clear survivability advantage at no extra cost. As tanks considering the relatively cheap cost of foot knights I would be hard pressed to use them over the the little tanks unless I knew I was facing open plain archers. Frankly though I am shocked by the cost of Halberdiers in paticular. I can only assume this is down too the 'advantage of cavalry' the unit is described as having which is, once again, not explained with data.
I wonder if researches increase the army strength cost of the units too? Seeing as all my researches that matter have been completed I wonder if someone can compare with a level 5 unit that does NOT have researches complete to see if any descernable difference can be seen.
Anyway I think I may cut this and paste it into a seperate topic latter as well as explore the options of doing it with the other armies so people can look them up. In the mean time, anybody got any info on trample damage?
