Seeing that there is no longer one big horde, but instead lot of small ones, hordes will not be a problem anymore. Even if they would be in crude, unbalanced form as they are in Divine Wind.
But imo, Georgia should have level 2 forts all over their country, to balance the fact they will propably still border few strong hordes... It would make it harder to kill them for hordes.
oh. i forgot about the later start date! maybe this colonizing horde thing will work after all
