The thing is at the level that ANET tests and theorycrafts changes is not at the level the rest of the world plays the game. I remember a quote one time where one of the devs said shortly after the game came out is that players were pushing the boundaries or have overcame boundaries that we never saw were possible. The never saw possible becasue the depth of their testing and is not very deep. And their change management system is not very thorough. They can make changes to the game without going through all the checks that most company’s go through and the do all the time.
