At this point I think we should all stop paying our ESO subscriptions till they fix this. We were just on last boss in vet DSA and servers crashed. We are not getting what we are paying for. Mass protest would probably get there attention. They can blame this on Microsoft all they want, this is a Zenimax issue.
this happens all and everywhere, vMA, Trials, BG
and it is annoying as I am doing BG and get a penalty for something that is sure ZOS error.
and I am EU, and it got much more worse after Morrowind patch
