Gondor definetly needs Borimir and Faramir (even though there's a submod for that it should be in the main mod). The models/bodyguard units for them are already done so just throw it in the main mod. And personally I think Gondor should for sure have Aragorn spawn as the King in a certain amount of turns. Eriador already has Gandalf and Frodo, they'll be fine without Aragorn, but I think they should start with him and he just eventually dissappears and swaps to Gondor.
Well to save KK all work with modelling Faramir and Boromir, he could include Faramir and Boromir Spawn.
Just look how good they look.
And this isn't commercial, i just thinks it's so good it should be included .
