In an ideal world where there was a shit load of players and KK had more money.
It would make more sense to make a server for those across the pond living in the states dedicated for them and another server for the rest of Europe. I don't think the whole timezones thing can ever be fixed.
With the current state of things this is just not viable. So people can piss and moan all they want, but there is no 'best solution' available.
