I'm new here, and judging from what posts I've seen like this, my ideas will get shot down really fast.. but here goes:
In my time in the game I've noticed that the latency between me and either server is not that much greater than most US/EU based games I've played, however the impact of this lag is much greater. I'm not sure why. Regardless of the reason, having an Australia-based server would decrease the problem.
From other similar threads I've read, there was a lack of usable & useful servers in AUS/NZ, but Amazon [with whom I believe the US server is hosted?] just recently opened a data center/server in Australia on the 13th of November. This should be viable server space for SK, and I haven't seen anyone suggest it, so I am now.
My original idea was to suggest making collisions in CW client-sided, but I think that would require a restructure of the game's architecture.
So there's my idea, feel free to blow as many holes in it as you want.
SK's next patch should include that in the main logging-on screen, there should be a "Select Server" in which the player can choose which server they use. But alas, it only extends upon to the Asia-Based SK; where there are a lot of Chinese/Taiwanese Players and you couldn't understand a thing if you're foreign and couldn't speak the same tongue.
The Servers to pick are: US/EU, Asia and AUS... IF it would be implemented, then many players would be able to enjoy SK more.

Lol, I'm just kidding about the above post. But, it would be nice though...
