I believe EB has already reached its hard-coded limit for the amount of provinces on the map. Personally I would like to see the province for the Sahara taken off and once again become a no-mans-land as in vanilla. Also, possibly combine some of the north-eastern most provinces into one another, considering the Yuezhi are being pushed out anyway. This would free up a couple provinces to add to either southern gaul, north africa, or possibly greece and macedon.
