Even if you have latency, it dosnt mean u cant pvp..... i know two players in my guild who play with 500ms, they still got 2k+ rating in s3. Maybe it will be hard to be number 1, but u certainly can be good in pvp even with the latency

Pve wise, there are quite a number of oceanic guilds in sunwell, latency is an issue sometimes, but the dungeons are still doable
