I imploded my human enemy empire, not AI. We always play on diety, so rev index has almost no affect on ai; it gets some many bonuses, that it takes many turns(tens of turns, my wife did it once) to cause even one ai city to revolt, while for human 2-3 turns is enough to put a city into revolt state.
Anyway if you are not messing with rev index, civics had them setup well enough. On a side note, only master of orion2 and galactic civilizations had good enough ai and it was dangerous. civ ai was horrible to begin with and now with additions it is even more hopeless. There's so many ways to screw up ai, that i never play civ as a single player.
btw if anyone wants to play mp game, please let me know:
