Oh Cumans would be awsome addition, any mods that adds new factions for Full map early or high era should have Cumans.I am by far not so good in history, but little i know that Cumans had huge inpact on nearby nations.Their Incursions were enough to keep nearby nations in check, even keep some smaller from being tottaly overun and had inpact on their military tactics.Although somewhere midt high era Cumans were destroyed by Mongols I think,anyways Cumans can from early era to late roughly represent nomadic Tatars incursions(Cumans,Pechengs,Kipchaks, etc)
I dont know if they need be emergent faction, becouse they were present at start of the game.But they should defenetly start as a horde.Are you sure that you would have them as emerging faction if you add them to CAE?
Poles and teutons move fast into Asia,Eleminating Russians in process, Hungary and Venice start eating at HRE if they dont enter war.Quite often I have seen Venice or Huns holding Vienna.If Venice and Hungary enter war its power struggle in Balkans.Until they are weakened, than Either poles or Byz use this opportunity to attack hungarians, Venice loose Venice either attacked by Milan or Sicily (but since vanilla, sicily isnt going after italian states)and soon after Venice, holdings in Balkan until they are left with Island or two.Oh I could rant forever now, suffice to say, I belive this faction might be key to balance expanding eu factions into asia that drown rus before mongols.Now only problem would be if they drown rus
Anyways...good choice in my mind...keep us updated plz,
so far your mod with new factions is only one worth playing and before M2TWR and Broken Cresant mod launches I havent seen anything much interesting, well renessance mod might be exeption,but that is.
