Replay feature for players' games

The overwatch viewer is great! But please,
Implement the replay feature for our replay, in game.

With the idea of improving my play, learning by my errors (and taking some more interesting funny and awesome clips),
I need that.

AND GIVE ME BACK OVERWATCH WORLD CUP VIEWER… i didn’t finish with that!

Didnt they just beta test that so it means its coming soon™?
