I notice that lately the game getting laggy, loading issue, and sometimes get a 504 bad gateaway. Its not just me though, I was blaming on ISP but most of my guild mate face the same problem. I don't know how to report/ complain about this so.. I'll put it here at least.. -,-
Right now I got loading issue, can't join World Boss.. I still hope I can enter Gauntlet though.
