I think that after you'e played the game there should be a way so you can watch the game back (in spectator mode) to see what mistakes you made or how you should have done things diffeently in PvP battles.
In my head if it gets implemented it will work in the way like when you've got eliminated but you can view the game from the very start.
This would also make it easier to catch hackers because if you have a hacker in your game you don't have to record it immediately you can play the game. Then when you've finished that game you can record the evidence, this would also make it easier to tell if there hacking because you can see all there fights not just the ones between you and them.
