Lower KD sizes -> people who were happy in their KDs get kicked out -> a good portion of those people leave -> large instantaneous player(core) loss in order to achieve slower player loss later on.
You can argue that according the the numbers the numbers of players affected is small, but those people that are affected are also most likely the ones who are playing because of their KD and part of the core that keeps utopia running. Not every player is equally important to the survival of Utopia, most come and go, the ones who are key to Utopia are the ones who have stayed on even though the game is outdated and OMAC's failure. You think kicking those people out of their KDs would keep them in the game?

First of all, I never responded to your post and you directly responded to mine, while ignoring all but the first paragraph. But yes I did read it and I agree that those sites you listed are a good idea. However I didn't respond because it was off topic, this thread is about reducing KD sizes and its benefits not advertising Utopia.
