Used pingtest.net and got 305 ping from NZ to Brooklyn. on another note isnt the server sea of sorrows closer to Nz as its a specified Oceania server so wouldnt that mean i would get less ping connecting to Sea of Sorrows??
I could be wrong here, but I think the US servers are all located in Washington state, so a better test would probably be to check your ping to Seattle. I think Sea of Sorrows is an "unofficial" Oceanic server more so that you know there's a high population of players from your timezone, rather than for technical reasons. The community decided that, not Anet.
Open your command prompt (type "cmd" in your Start menu search bar) and type "ping www.guildwars2.com" (no quotes). That will give you a better idea as to your latency to the game's actual servers.
