Mongols is surely strong civ. But not the best civ in the game. It have so many strong point but also have weaknesses such as mid-game, too much relying on hunt, bad at trash war.
It seems like “Huskarls counter archers so hard is wrong because archers are supposed to counter infantry” Or Cataphract wreck halbs and Camel is wrong because they are supposed to counter Cavarly" I mean, isn’t it purpose of many UUs? Introduce some other mechanics in the game. Make UU just other version of generic unit is not a right move in my opinion. Difference between civs become too obscure in this way.
Also, Chu Ko Nu and Kipchaks already better vs Rams than Mangudai. Bonus damage against seige is selling point of mangudai and make them different from HCA. And sniping trebs by mangudai is not that easy if opponent play properly. Mangudai is strong but Fragile. only 4PA with lacking last armor upgrade and almost 2 shot by Halbs when not properly microed. If huge numbers of Halbs are protecting trebs, mongols player should trade like 15-20 mangudai with just 3 trebs.
It is hard to evaluate the effect. The crazy fast feudal of mongol would be slower but hunt itself is 2nd fastest food source. It gives less powerspike but more consistent bonus. But I don’t like changing civ mechanics. Sure mongol rely on fastest hunt but it almost expires in Dark age and most civ ahead in mongol if mongol player not attack early using their powerspike. I mean, it is already balanced in this way and why we need change? I don’t think changing economy and powerspike of all civs more similarly is right move.
