While you certainly have to give that team full credit for the amazing teamwork and class synergy that enabled them to accomplish such a one-sided victory, this will get nerfed/patched, or at least it should. Unfortunately, it's simply not sustainable for the current state of PvP in this game and would negatively impact the player experience for far more players than it would be enjoyed by those who are playing at that level. You cannot justify something in PvP for the 5% of the player base that's capable of it to the detriment of the other 95% without have some degree of separation. There is no ladder system that forces the truly amazing teams to move up and play against other equally skilled teams, and most players who PvP in this game are merely jumping into queue with 5 other random players and will never have any hope of competing with a team like this one.
