That's the awkward thing about this game. You get a lot of FPS players who have never played an MMO or anything like one so they want things like trading and weapons from old content to be upgraded. They simply don't understand or even care that the game requires for you to keep progressing so that it can thrive down the line. The sad part is that I sometimes worry that Bungie will cave in to the casuals and ruin their game in the process.
