Experienced the same connection issue from SEA.
My ping has always been high, but there is no lag problem for me if I manage to log in to the game.
However, I keep getting disconnection issues:
- When changing map, disconnected or eternal loading screen
- When starting an instance (story instance, etc.), eternal loading screen
- During World Boss fights (no prior lagging), sudden disconnection.
- When logging in, eternal loading screen.
