Distance to the servers is a speed of light thing, no matter how good your connection is, even if it's all fiber, there is the distance factor.

I live in the middle of NA and my ping on Google Fiber is 49 ms to the NA DC. NY to LA is 63 ms latency and that is going to be as good as it gets due to speed of light. It isnt unreasonable to ask for the netcode to be optimized to be 100% playable at 100 ms latency.
