Small Suggestion but may make huge difference
From http://www.guildwars2guru.com/arenanet-tracker/topic/256859-wvw-end-of-culling-and-pve/
ColinJohansonThe initial release of this system will be for WvW only. There are additional complications we need to solve with PvE due to the number and variety of creatures on screen that WvW doesn’t need to account for. Later this year, we’ll be expanding as much of the changes to the PvE open world as we can as well.
So it seems that they are working on it, but it’s somewhat more complicated than W3 was.
