No its not, you propose a solution the short term, making them unbalanced(too expensive) in the long term whenever taleworlds fixes them or works out the mechanics and basics(if they ever do).
Come on dogl, how many big ass horses have you seen in competitive high level in Warband in so many years, probs can be counted in 1 hand and its just the 1200/1400 gold ones after a round or two stomping. That's not viable and the hunter was just slightly worse. Mercenaries module is the best example, best players kept using a hunter despite all the options and not because of the prices, but because of the stats and how good hunters are even when in comparison to war horses/heavy ones.
180g isn't cheap, its very expensive and will force you to go almost peasent except for some factions & classes, but this should be looked into and balanced AFTER mechanics and basics are worked out as said. (Right now it's OP but because of the mechanics being overpowered themselves, damages favouring cav, classes and perks being strong for them, and the mechanics to stop them malfunctioning specially when punishing a really hard to be stopped cav, you already know this ogl writing for others I guess)
I agree, it really does, same with some golds, but again, I think the order of the changes is important, it's the same with damage. What's the point in saying this unit needs 20 armor instead of 30 and 40 damage instead of 35 if damage inconsistencies and damage absorbtion is still a thing?
