Have the random load screens ever been addressed by zos (not just the long load times)? Its been happening for so many patches now and it seems even worse.
Specifically on PS4 NA you hit so many load screens when taking a keep, when it flips, during defense, and even when the keep has zero action at it. We all see the keep walls upgrading back to back. This is causing either both alliances to freeze mid fight or just one and the other faction gets to kill everyone standing still.
if the animation of upgrading is causing the problem maybe you should just remove it?
