That is no exaggeration.. the loading screen issues in Cyrodiil are an example of epic suckage.
Every time a keep flips -- loading screen.
Every time an inner postern get rebuilt -- loading screen.
When you die or port -- loading screen.
And those are just the expected ones. Then they are the "well it's 7:14 on Wednesday so you get a loading screen" ones.
And they can take 5 minutes to clear. A third.. a full THIRD of my last hour in Cyrodiil has been spent on loading screens. ZOS, are you EVER going to fix these?
