That, and because a lot of the feedback I'm seeing about the tag system seems shallow. It would be better if people took the time to really explore the new tag system, and took the time to gather meaningful, constructive feedback. The fact that the monstrous amount of work Bungie's dev team put into this isn't being appreciated makes me sad, but it also makes me sad that the community that prizes Bungie as being innovative and industry changing is cringing that Bungie made an innovative change to how Bungie.net works.
