OK sship developers, I have found some "bugs" or incorrect things regarding Byzantine recruitment, which could be improved for the next version:
1. Regarding the Tagmata or imperial units, it is correct that the katapraktos and the Varangian guard are recruited in the Imperial Palace of Constantinople, but the "vestiaritais" should also be recruited because they were the personal guard of the emperor together with his mercenaries of the guard Varangian. Thus we would have the 3 imperial units only being possible to recruit them in Constantinople and in the Imperial Palace (if Jurand does not want to create another maximum level of the chain barracks called "Tagmata Barracks").
2. The infantry units called "symachika tagmata" are not possible to recruit in the game, I think you have removed them by mistake, these units were a mix of peoples like Serbs, Bulgarians, Slavs, Greeks... I think it would be nice to include them on the 3rd level of the castle barracks.
4.Archontoupolai at that time were already anachronistic so they should be eliminated, in the nikkosaiz roster these units were eliminated, on the other hand more mercenary units such as Alans and Turkopoles would be added. If you want to keep them present in the game it would be convenient to have them inside the "orphanages" building as they were the orphans of fallen military officers.
5. Add the Gasmouli unit (Italian-Greek crossbowmen) in the archery of the castles (4th level), and in the cities too but in their highest levels of barracks.
6.Add Menaulion pikemen units to the game, these Byzantine pikemen units were widely used along with skoutatoi in Roman formations, from the beginning of the game, recruitable in cities (high levels of barracks)
7. Finally I have realized that the SKOUTATOI units (swordmen and spearmen) can be recruited in the cities, this is a success since they were the professional units of the Romans (their modern legions) but they should ONLY be recruited in HIGH BARRACKS LEVELS (militia barracks and army barracks), at first only Constantinople would be able to recruit them in their barracks since they are powerful units and require a high level of barracks, currently I have seen that some small cities like Arta or others with low level of development they have it, (2nd level of the barracks), this is a mistake and should be modified, only large city levels (large city and huge city). On the other hand, the castles could already produce these units from their 3rd level of barracks.
HERE IS MY LOGICAL AND HISTORICAL PROPOSAL FOR BYZANTINE RECRUITMENT:
+For the city barracks I think they should be:
-1st level(TOWN WATCH)--- 2 kontaratoi
-2nd level(TOWN GUARD)--- 2 kontaratoi, 1psiloi toxotae
-3rd level(CITY WATCH)--- 2 kontaratoi, 2 psiloi toxotae, 1psiloi acontistae
-4th level(MILITIA DRILL SQUARE)---3 kontaratoi (1 experience), 2 psiloi toxotae, 2psiloi aconstistae, 1 menaulion pikemen
-5th level (MILITIA BARRACKS)---4 kontaratoi (2 experience), 3 psiloi toxotae (1 experience), 3 psiloi aconstistae (1 experience), 2 menaulion pikemen, 2 gasmouli , 1 skoutotai spearmen, 1 skoutatoi swordmen
-6th level(ARMY BARRACKS)---5 kontaratoi(3 experience) , 3 psiloi toxotae (1 experience), 3 psiloi aconstistae (1 experience) , 3 menaulion pikemen(1 experience) , 2 gasmouli , 2 skoutotai spearmen, 2 skoutatoi swordmen
+For the castle barracks I think they should be:

-2nd level(GARRISON QUARTERS)--- 2 kontaratoi, 1psiloi toxotae, 1 peltastes
-3rd level(DRILL SQUARE)--- 3 kontaratoi(1 experience), 2 psiloi aconstistae (1 experience), 2 peltastes (1 experience), 1 skoutatoi spearmen
-4th level(BARRACKS)---3 kontaratoi(2 experience) , 2 psiloi aconstistae (2 experience), 2 peltastes (2 experience), 2 skoutatoi spearmen, 1 skoutatoi swordmen, 1 symachika tagmata
5th level (ARMORY)---4 kontaratoi(3 experience) , 2 psiloi aconstistae (1 experience), 2 peltastes (1 experience), 3 skoutatoi spearmen (1 experience), 2 skoutatoi swordmen(1 experience), 2 symachika tagmata(1 experience).
+For the IMPERIAL PALACE (TAGMATA): 2 katapraktoi , 2 AngloVarangoi guard, 2 Vestiaritai, 2 Anglosaxon huskarls (it is possible that these huscarls are also recruited from the barracks but only in constantinople)
+For the Alchemist Laboratory: (ONLY IN CONSTANTINOPLE AS SECRET GREEK FIRE)
1st level--- 1 Siphonatores
2nd level--- 2 Siphonatores, 1 Naffatun
+For the STABLES of the castles:
-1st level(STABLES)--- 1 Mounted akritae
-2nd level(KNIGHT STABLES)--- 2 Mounted akritae, 1 Vardariotai
-3rd level(BARON STABLES)--- 2 Mounted akritae, 2 Vardariotai, 1 latinikon
-4th level(EARL STABLES)---3 Mounted akritae(1 experience), 3 Vardariotai, 2 latinikon, 2trapezuntine horse archers
5th level (KING STABLES)---4 Mounted akritae(1 experience), 3 Vardariotai, 3 latinikon, 2 trapezuntine horse archers
* The regional units of each area would be added, such as Magyar horse archers, Alans, Turkopoles, Pechenegs...
+For the arcades of the castles:
-1st level(BOWYER)--- 1 psiloid toxotae
-2nd level(PRACTICE RANGE)--- 2 psiloi toxotae, 1 mourtatoi
-3rd level(ARCHERY RANGE)--- 3 psiloi toxotae, 2 mourtatoi, 1 gasmouli
-4th level(MARKSMAN RANGE)---4 psiloi toxotae(1 experience), 3 (1 experience) mourtatoi, 2 gasmouli
*the regional units of each zone would be added, such as hunters, slavic javelinmen, armenian archers...
If you like the proposal, tell me, I think it makes its recruitment quite historical and logical, maybe something needs to be improved, if you want you can add it to the byzantine thread, in guides.
In addition to making recruitment progressive according to their levels, we would also make the city of Constantinople very valuable to have for the Byzantines, for having its elite units and its secret of Greek fire (it would also include in the Byzantine port of Constantinople the Ships of Greek fire as unique to their port)
+Another curious proposal would be that in order to have the Trapezione horse archers throughout the Empire we would need to conquer TREBIZONDA (where they originated) I don't know if this is possible but in other mods I have seen that conquering a settlement gives you access to a type of units , and if you lose it you can no longer recruit them, this would be quite interesting to have, it would be like a supply of regional units for your entire Empire and your army, same case with African units that if you lose certain settlements you can no longer recruit them.
I hope my proposals will help you, especially because I really like playing with the Romans!!!
