This is a fantastic change. I do feel for those who were towering above the rest because of course that's a great place to be, but a change like this was sorely needed. There should not be 60K dps increase legendaries sharing the same drop chance with -5K dps legendaries.
You shouldn't need that one great legendary or a couple decent legendaries to be competitive, and there were a lot of consequences at the higher end player base due to this problem. Blizzard recognizes this, and it's absolutely a great change.
