It was only a matter of time with the way blizzard was scaled gear things like this would happen. Also if blizzard did there number crunch like they wanted to before good chance this wouldn't have happen.
And to people saying this is a exploit. It really isn't everything is working the way it should but the problem is blizzard did not see it working this way. Only way I would say this is a exploit is the way player's are going into the level 90 raids.
feel free to disagree but that's my opinion.
