MORE SERVERS IN NA

Okay, they don't have to be completely different server and I don't know too much about this type of stuff but like, China has like 20 different servers and NA literally only has one. Why don't they just split it into 3 so we won't have like 60-80 ping consistently and just over all lower the ping of every player. I know 20 ms difference doesn't seem like much but it just feels a whole lot smoother at 80 ms than at 100 ms. I just feel like there aren't enough servers in NA and that if there were the ping difference would be pretty awesome.
