They need custom games and a theatre mode. Seriously, the make the Crucible out as a sport between Guardians and then they don't let us have our own scrimmages against mates/ other clans, nor can we re-watch our moments of glory from different angles. Was rather disappointed with the lack of both actually. Also disappointed in the lack of Forge like they had in Halo, community made maps, that would have been fun in Destiny.
