Sorry SE, but endgame won't work if you don't fix something.

I am also playing from the UK, on the Japanese servers no less. However unfortunately the issue is just as prevalent if not more so. I ran a test specifically on AoE attack avoidance and off-GCD ability responsiveness on Legacy Ragnarok EU where my 1.0 character is and Atomos JP, which is the server I now play on. Things are equally bad on the Japanese server.

I am wondering how many people posting in this thread are either from the EU or from areas far from the NA and JP servers.

It "doesn't" matter where you live or where you connect; sure these facts affect latency as well, but the pings are not the issue as it has already been stated, the real problem lays into online game/networking design, at the server end.
