Hrm, what map are you playing on?
The original Exiles map or Isle of Siptah? I only ask because Siptah map is having some performance issues atm , you can mitigate this by tweaking your game setting (by selecting performance mode , for example)
If it’s the exiles map, then maybe your ping is too high.
This might sound very counter-intuitive but go with me: try using Wi-Fi instead of a direct broadband cable connection, see if this helps with the rubber-banding as sometimes it doesn’t seem to cope with a higher speed connection (it’s totally backwards, I know, but try it)
Hope some of this helps.
