@MayMay @Queue thanks, you guys are correct I think.
I figured it out from the serverlist_recent.xml file in the game folder and used https://www.iplocation.net/ to check the server location. SEA and EU servers are indeed still in their intended locations though the IP addresses changed at some point.
Fedimian region (Frankfurt) IP: 52.29.228.194 —> 52.29.227.229
Telsiai region (Singapore) IP: 52.77.112.61 —> 52.77.36.116
Silute region (Sao Paulo) IP: 52.67.15.170 —> 52.21.229.204
Only Silute is evidently f*cked seeing things go from this…

…to this…

Anyways, I brought this up because from some reason the game, specifically on Telsiai server where I’ve always played, suddenly decided to give me a ping of 0.30+ (I used to get 0.10 or even less to 0.20 at most where the game was at least playable for me) when I tried to login again to catch up with a friend in-game. It made my QS a joke, and it’s not fun anymore to wait for the 2nd attack animation before your damage or skill actually lands.
Should I start considering using WTFast or something similar at this point?
My other games (Dota2, Battlerite) doesn’t seem to have such issue. I’ve checked my ping via command line as well as online speed tests and they give consistent results that I’ve always had. I think this can’t be because of my ISP.
