Zoning itself is a major annoyance that most people just accept. The ten seconds or so of black screen, not being able to see any messages in chat, the time after zoning when you can't see items because they are still loading, the 5 seconds of being frozen every time you zone on Xbox, etc. If you add up all the time spend zoning since first playing the game, each player may have spent hundreds of hours looking at a black screen.

And to make it worse there are zones where you have to watch an annoying cutscene every time you zone, such as Ru'Lude Gardens into Mog House, Tav Safehold into Sea, every time you use a Runic Portal, etc.

I'm guessing zoning is such an integral part of the game it is something SE would be unable to fix, but they could definitely get rid of some of the zoning cut scenes.
