A group of 3 of my friends and me with another group of 4 we found noticed the syncing of the raid is off bad at time. It was up to about 10 seconds off at times. We all have had no problems with server lag that bad anywhere else. At times, in the party I would hear a boss was on me but when that was said it was way after it was. And then it would get to where I was way behind. No way to do a raid like that.
There are times it is not bad but when it is it is when the raid goes to crap and everyone starts dying.
I guess this is what Ubisoft gets for not testing it other than in house. Fix the server lag/sync problem and the raid will be doable.
No way a video would show anything. We would have to have third party equipment to show it out of sync because Xbox doesn't record party chat. Never say any slow downs or speed ups. Just from the party chat hearing 3 people say get off the turret when that was after I was across the room then the same happened the other way around.
