Rubberbanding

Rubberbanding is a colloquial term describing when the player appears to be running, but then instantly teleports back to where they was standing, similar to the Shadow of Haste skill. For other users, the player appears to be standing still, which is a great annoyance, especially in PvP.

This is most common in Alliance Battles, but can happen anywhere. It is generally, although not always, a symptom of lag.
