So by announcing this recent change, you make Legacy gear obsolete, but you don't address problems with Loot 2.0 gear. If the change had been to address Loot 2.0 gear to make them more attractive and better, you still make Legacy gear obsolete, thereby killing two birds with one stone.
Like many others have said before me, had the previous sentence been true, this conversation wouldn't exist.
Couldn't have said it better! Make RoS legendaries more awesome!
