Bungie, You recently had a shirt for sale on your web site that could only be purchased by people who had finished, I think it was the Dawning Book. In a similar vein, I would like patches sold that would only become available to people if they had completed a specific task or proven a level of proficiency. For example, a patch for each raid that is only available if you complete the raid (on hard mode?). Or, likewise, patches for people who have achieved 10,000 or 100,000 kills with a specific gun class. Keep them cheap, like a dollar or two, so even kids can afford them. The hurdle to get these should be skill, not finances. I know I play Destiny with a lot of people I know IRL and it would be fun showing off my latest achievements when we get together for a pint.
