I too think the warmonger penalties are overkill, especially early-game and especially where city-states are involved. I think that's what makes being forward-settled really really ing obnoxious. You've either got to roll over and take it, or have the whole world despise you for cleaning up one of Pocatello's, Hiawatha's or Shaka's little ******** towns that's in your way. Sadly, the AI has no recognition of "oh man, that'd piss me off too, go get'm!", so instead YOU'RE the jerk. In a similar vein, I think the warmonger penalty against city-states shouldn't be calculated the same way as a normal Civ's. The first one or two you take should be mildly off-putting, but only really piss someone off if they were allies. Maybe the calculation should be in relation to the number of city-states left as a whole, as though they're one civ collectively.
