Netcode fixes for next expansion?

[royox]

What is wrong with the netcode?

I have absolute no clue...but isn't the "netcode" one of the reasons why when you use DRG's Jump or NIN teleportation and there's a hole between point A and B, you fall? I played other MMO's where the classes with "charge" or "jumps" could use those skills to reach points they normally couldn't reach by walking, or could use those skills to jump over a hole during the fights.
