They are not going to take action against the vast majority I can assure you of that, only the exception cases that have been the worst offenders. It's such a big flaw that everyone on an unbalanced server that has been queueing has been getting it. I've been watching it part of the day on a live stream. I'm sure a significant number of people, more than they can effectively act against have gained from it by this point.
I tend to agree with several posters here, in that its the journey not the destination, but the other comment that rings true is end game, this is PvP (on PvP servers) and we are the content...level means everything from a PvP standpoint and gives these people a clear advantage.
Terrible bug to ship with.....
