There will never be an addon to do this, unless there is a note portion attached where players can actually critique indidividuals and leave a lasting "player score". Gearscore is nothing more than a calculator telling you what you should be able to do in a certain level of gear, you're not going to get much more out of an addon.
I find it incredibly offensive that someone who lacks the knowledge to understand the simple difference between your and you're, or that realizes that logic is applied to everyone regardless if they understand it or not is making judgment calls about me and my life. I care if people hate gearscore for the wrong reason because it's bringing intelligent discussion on these forums to it's knees. Logic is not "my standard of reasoning" it is THE standard of reasoning for anyone who lives in the physical world. There is also a difference between saying "fuckin chair" after stubbing your toe, and saying "fucking gearscore keeping me out of groups" and creating threads about it. One of these actions is completely in the moment and innocently uninformed, and one of them is willfully ignorant, makes little to no sense, and is a blight on intelligent debate.
Well, you're welcome Earthson. That was my goal
