PvP Game Data Recording Feature - Like Halo 3 had IN 2007!!!!!

[Chromazene.4807]

I'd really like to see a feature where game data for the previous 20 games is saved in replayable 2MB or so files.  You know - a feature Halo 3 had back in 2007?  That way it will be much easier to identify cheaters, AFKers, and griefers (and so GMs cannot use the excuse of "we have to see it!" to avoid taking action).  Also, it has the side benefit of depicting what builds players use to kill you and so on.  There's already a spectate feature that depicts this game data live to ANet partners, but a feature that would make files replayable after the games have concluded would be nice.
