Iam used with high latency but 500 ping on average is waay to high even on eu server, I try once at west server (ultros) and iam stuck with 260-320ms, its the bare minimum for me until i move to jp server tonberry and now i get 100-120ms on average.

If you are ausie shouldn't you be at japan server like elemental instead of eu server? And again 500 is too much, even if you met angelic people they going to decline you in the future, 300 is already pulling it and 500 is pretty much unplayable even worse if you are a key class in party like healer.
