I doubt that TW will make these changes when the game will be releasing in a month but here it is; the Khuzait t2 cav unit should be changed to a melee cavalry rather than being a ranged cav unit. Horse archers were probably some of the hardest troops to train, even though Turco-Mongol peoples apparently trained kids to hunt on horseback from childhood (I'm not a historian so I can't confirm or deny the validity of this information), having a power-spike in t2 is not healthy for the balance of the game.
My other and possibly controversial change is scrapping the non-noble horse archer troop tree (or maybe the noble tree but Aserai Faris tree already exists and we need more unique noble troops) and making them into lightly armored cav skirmishers (so cavalry with throwing weapons) AFTER nerfing throwing weapons. There is no reason for there to be 2 horse archer troop trees in the same faction especially since there is literally no upside to having the commoner horse archer variant in your party. As it is right now, recruiting noble troops is probably easier than recruiting a specific commoner troop. (It also boggles my mind that Jereeds are an Aserai culture item despite them being historically and culturally part of Turkic armies. Why give this item to the Arabic faction rather than the Turco-Mongolic (+Hunnic) faction? They are not even equipped by Mamlukes which were literally slaves with Circassian and Turkic origins. Cirit, literally Jereed, itself is an equestrian sport popular in Turkey and other Turkic countries). Just give the Khuzait horse "archers" javelins or something instead of bow & arrows ONLY IF the throwing weapon damage is nerfed, otherwise, the already OP Khuzaits would just become stronger.
