I think it would be a good idea to implement two different type of killcams that after you die you can switch between the two. One could show your opponents POV before you die that way you could analyze what he or she did right but then there could be another killcam you could choose that would show you your POV before you died. This would help people better analysis what they did wrong and how to improve. It would also be a nice little addition to the game. Let me know what the halo community thinks!
