Playing the jerk here.....
Well yea cause the Xbox one is better server wise then PS4.
On a serious note...maybe there are limitations to how each is performed by platform.
Maybe there are that many more players on PS4 so it takes longer.
Maybe ZOS is doing the PS4 while Xbox is updating the Xbox server so it takes longer
Maybe....the game is more compatible with one consoles server than another.
Just speculating, I have no clue but hope u guys get reduced downtime in the future. Maybe ask on ZOS live now so they answer this today :-)
