7-10 is what I am currently arguing for after having explored most of Brennus's lands. However, I do not suggest going for Trebs anymore as I have seen that Cats will do the same/similar job except that they die.
In the test I just ran, I put 3 archers in each city and one axe in mine. I put stacks of 2 and 3 of units in between the cities I captured and they all went to the cities I didn't capture. He ended up with around 13 units or so in his capital without thinking of attacking.
Why don't we want any vassals?
We are going to eliminate two AI. Leaves us our continent to ourselves. We need two victory options in one turn. Culture may be one of them. The other have to be from Domination OR Conquest, Diplomatic OR Religious and Space.
Space should be out of the question because it results in us having to research an extra 5 techs, invest hammers in Apollo, build the parts and then 10-12 turns to launch. That leaves us with Diplo/Relgious and Conq/Dom. Having 2 vassals (along with our pop and land) opens the door to BOTH Diplo and religious. Plus, AI get era bonuses, but their problem is they try to research everything pretty much. So if we had an Emp AI (a good one, not **** like SB) vassaled to us, we could have him research X whilst we are researching Y meaning we won't have to research it.
