If you experience high ping, you should look into paying for a gaming VPN. These exist to eliminate the latency trips that your network ISP has to travel, by optimizing the network pathway.
The server we run is in Canada and if you aren't inside Canada, the pathway to it could be really bad. This is something we can't fix, which is why we will look in the future to provide an alternative server for EU region and US. It just is not something we can do with our budget, time, or resources at this time.
The only real solution is to pick a good VPN/proxy and use it for the time being.
