region specific units

will there be any region specific units? for example in r:tw there was spartan hoplites and now RTR is doing a whole zone of recruitment thing

i was thinking maybe a similar thing could be done in blue lotus for example monks can only build there best units on 'monk' island and on the mainland they make levies? or something like that
also the japanese could make ninja only in their specified areas making it a good way to cut back on ninja but still allow them
and another: all factions can only build their major units in their original provnces this will make the factions even more unique and stop fast spreading like in r:tw where i just took all of greece in 10 years (as brutii (this made me look for a new mod in the first place :bow: ))
what do u think?
