I have just went through an Urgent Quest on the Xbox One and been into a couple event Quest and had multiple runs to where I saw a couple Maxed level 75 Players Quit during Start of Countdown and not Help finish a Match. That is Disrespecting Players that works hard to get to that level to earn that right to play in that difficulty mission. These high level Players that don't want to help others that earn that right to be in that Difficult mission don't give them Credit. I got cheated out of an Event by Level Capped Players Quitting in a Super Hard Mission I want my credit I deserved from these Quitters that I was robbed from.
