You guys really need to know why byzantines were denied of bloodlines first, they were one of the best civilization in aok, but right now ethiopian camel>byzantine camel, not even a fully upgraded camel is still better than the one from byzantines it might only win cost effective but if you are going to invest in camel line better to invest in stronger camel line, such as indians, malians, saracens, persians, berbers, chinese, tatars etc.
Byzantines are not even close to the 15 best civs for 1x1, same like goths they are just a civ supposed to win with trash, but this is no longer aok or aoc, new units are in game with new bonuses, byzantines are outdated, their trash is not even competitive today. If the meta was like in 2001 to 2005 when big number of skirmishers was enough to win games in feudal age then i would agree that they are fine.
Bloodlines would help their cavalry line for team games, just by removing 10 HP from the cataphract, no one would complain, heck if you are tired of all its units in tec tree remove heavy cav arch.
About cataphract, its concept is oudated aswell, super expensive and weak vs other mounted units, ranged units counter most efficient infantry line, until AOC catas were decent and would put a good fight vs paladins but they would still losing, but on DE cataphracts loses to almost everything, eles, stronger camels, civs with attack bonuses like lithuanians and malians. It was true that catas countered archer back at the aoc days because they were able to break into the formations and cause the trample damage, but now they canât break into formations and die miserably without hitting in most cases.
Balancing cataphracts to the new units in game requires a reduction in logistic price and even the elite upgrade, if they get bloodlines they should lose 10 hit points, even gaining 10 HP as result of the bloodlines they would still losing to leithis, boyards, eles, most paladins, indian camel, etc.
No one is asking for economic bonuses for them, just to give them bloodlines and price deduction for the UT, that wouldnât change the civ identity and wouldnât make them OP.
But if they refuse to give them bloodlines, just like they refused to give husbandry to teutons, then change logistic, it should apply to all their cavalry line, then it might be worth the high price.
