This is a good change but doesn't have much of an effect on the victory since favors don't matter that much to win diplomatic. All you need to win early votes is to have more favors than the AI that have more favors, which isn't a lot and is pretty easy to achieve, then later it's easier to time your victory than try to beat the AI once they all go for your jugular, which is impossible to beat depending on how much players you have on your game. There's probably a lot of players that play on standard size maps, in which case they wouldn't be as affect by the problems the diplo victory have as someone who play on a huge map. The main problem with the victory is that it scale poorly with the numbers of players, which can lead to widely different experiences, from having an easy time to drowning really slowly on a sea of frustration, all because of the AI pilling up to stop who is winning, so it's more about the map size than casual vs hardcore. I hope the next patch will be focused on the congress, it does need a lot of overhauling.
