I believe there are major improvements with the release of servers (asia, na, eu).
Sadly,despite what you called "Asia" server, I only managed to get... 400ms ping! Where is the current Asia server location? If it's in the middle east or west india... By all means I believe that it's bad decision to put Asia server there. You need to put Asia server in the middle of high population countries, which ideally it's somewhere around Hong Kong/Singapore/Hyderabad. I can connect to servers around those area in other online games and easily reach 50-150 ms ping. 400? It's like I am connecting to Ireland instead of "Asia"
