Rubber-banding
From Guild Wars Wiki
Rubber-banding or warping are slang terms used by some players (mostly (relic) runners using speed buffs) to refer to having one's moving character suddenly appearing back where they started from (or at an earlier position).
Rubberbanding not only happens when you get body blocked by a group of enemies, but also when you are simply walking a path. you won't notice this happening because on your screen (as client) you passed that group and are running on, but infact you didn't...you are still blocked.
This is caused by network lag, where the server did not receive the appropriate signals from the game client that one's character had actually moved. The client is unable to catch up with the server (due to a high ping).
Examples:
- You are taking damage while you seem to be far away from the blockers (on the client)
- When on the client you are attacking a foe (and nothing happens) which is not at your REAL location.
- Your ping is higher than 1,000ms (icon turns orange or red)
- You are moving and are often "warped" backward.
When you experience rubberbanding, often the best move for you is to cast healing/protection spells and wait until your client receives the right information from the server (the information that you are blocked or the information of your real location).
A "remedy" to this is to click on the place where you wish to go, as most of the work is done serverside, and there is far less of a chance of rubberbanding. This may also be fixed by using /stuck because it shows you where you really are.
