Just break things down here
1. There is already a west coast server that works very well, just no one uses it because there are only like 5 good WC players, some of which are only semi-active
2. DCT works well for the most part, and is in chicago. Unless it goes down there is no reason to add another chicago server
3. Realistically most people won't get good ping to a toronto server, its further from most people than the New York option.
4. Really the only issue with New York server is it alienates West coast and mexico from being able to play. Personally I think NY is fine, because I am fine with playing on 6 frames.
5. Florida helps players from the south, and most east coast players would get 3 frames(most florida players got 3 frames to FU, at least, but I am probably wrong to assume EC players will get 3). It is also closer to mexico than NY is.
Whatever is chosen, PLEASE MAKE SURE THERE IS NO 60MS+ FEDEX ISSUE ON LAN
