I honestly don't know what the point is of buying a 50. The only thing I can think of is to look cool among your peers. You'd be surprised at how rampant buying/selling level 50s is. Like I go to this Halo 3 message board sometimes (halo3forum.com), and there's a forum there designed to add people as friends so you can gain people to play with, right? Well I'll make a thread like "Need 3 good teammates for Team Slayer to get to 50." and most of the responses are, "I'll get your 50 for a 1 month code" or "You can add me and I'll play with you but you have to give me 1600 Microsoft points." - it's fucking retarded.
