I've been thinking about this and im not sure if this could be easily done but if implemented the benefits from a social angle could greatly increase the multiplayer recognition and be beneficial to those that upload tutorials and tips to youtube. Additionally the 'Dares' and Bragging rights could feature a heavy part too.
Simply put a 'Theatre' or Spectator (free roam) mode.
Like a popular shooter (that shall not be named) the added ability to capture great kills / streaks and/or stuns with an addition to save/send or upload could be great. You would also be able to review your own match / play style and see what aspect would require further polish and work towards becoming a much better player with honed and improved techniques.
If playing a game (especially new players) and other templars ALWAYS seem to get the jump on you from no where. then this can offer the vital piece of the puzzle to find out why and not make the mistakes again.
What do you think?
