I'm an Australian player with a ping of around 300 when in Cyrodiil, up to 500+ when in fights. A common occurrence is the character suddenly not responding to any input at all, which is usually just before being attacked by 1 or more opponents, with death usually occurring within 1-2 seconds of the visual display of attacks starting. In these circumstances, the death recap often shows one player having done 5 different attacks in what seems like 1-2 seconds, or of course multiple players all having had a hit within that one second. I can understand multiple opponents all attacking at the same time resulting in so much incoming data occurring that the game pauses my character while it tries to process it, but I've never understood the same thing occurring with just one opponent.
So I'd like to understand what attacks and/or effects there might in the game that don't necessarily have a visual effect, but which result in a high-ping character being overwhelmed by incoming data, so that the result is it no longer responds to any input. It just stops moving, can't roll dodge, can't use any skills, can't swap bars....
If anyone has any thoughts or insights on what might be occurring behind the scenes that results in this behaviour, i'd be very interested in knowing, and maybe then working on how I can mitigate what's occurring (without needing to move to the US!).
