This is to demonstrate how bad things can get when trying to go through a dungeon. Clicking everywhere can be noticed by those small circle-dips that appear and disappear all over the ground (where I was clicking to demonstrate that I wasn`t standing still on purpose). The rubber-banding is seen towards the end of the video ni particular...attempting to move forward sets you back several steps that you were at maybe 5-10 seconds ago.

Update 04jan015TL(2011CE) - A significant percentage of the latency seems to have disappeared today (after weeks and weeks and weeks of it affecting us all). For me it seems to have anyway. Rumour has it that the employees have returned from a Holiday break/vacation (I guess Nexon America is probably not a huge company like Square-Enix) and are working towards a permanent fix.
