Yes, RCav have a 1.3xDmg modifier against Archers and additionaly, Archers have a penalty towards Raiding Cavalry .. 0.9xDmg
For 55W and 35G, you get a 60 hp Toxote, with 15% HackArmor.
While for 40F and 50G, you get a 105 hp RCav, with 25% PierceArmor.
For the following, the assumption that "55W and 40F are neglegible differences" will be used.
They both have equal build times. So a 35:50g Ratio means for every 10 Toxotes the Norse can have 7 Raiding Cavalry.
Time it takes a RCav to kill a Tox:
60
--------- = 6.79 seconds (Rounded to two places)
8x1.3x.85 (HDmg x Bonus x Toxote HArmor)
Time it takes a Tox to kill a RCav:
105
--------- = 27.78 seconds (Rounded to two places)
7x0.9x.75x.80 (PDmg x Penalty x RC PArmor x Accuracy)
That statiscally means, that 1 Raiding Cavalry should last as long as 4 Toxotes, in a One-on-One encounter.
OR that 7 RCavs as long as 28 Toxotes! (While only 10 Toxotes can be built for the same gold).
28 Toxotes -> 980 Gold
7 RCavs -> 350 GoldI dont know what you guys are doing, since i dont have the retail, but really the numbers suggest that for MUCH less than HALF the gold spenditure, the norse RCav should totally decimate the Greek Toxotes (One on One).
