We routinely have the Team Optimizer rank gear that in such a method that it suggests replacing a legendary with a lower level item. When we looked into it more it appeared the reason it was ranking it that way was because Mr Robot was suggesting completely different legendaries to use from their inventory.
This has become one of the highly debated topics with my group. The short of it is that they would like to set which legendaries per spec they wish to use, much like how they can set their own stats weights and use then for their public profile.
Is there any way that the choice of preferred legendaries per spec can be set and saved as the public profile?
