The rebellion aspect is a little over the top don't you think? I had 2 uber stacks of units, 1 era ahead of me, pop-up next to my city. I somehow beat them next turn, AND now I have 2 units from anywhere in the vicinity of the city join the rebels(the city is happy). This has gone on now for 5 turns, and is hardly realistic when you consider it is ONE city. If rebellions are going to stay this extreme, then I reccomend adding "decimations" and crucifictions to the roman arsenal. That should neuter the rebels a bit.
