I'd like to know about the enemy having wallhacks without watching myself die in the killcam. Widowmaker is usually so far back when she uses it you don't hear the voice line and it really hurts trying sneaky positioning if you never know when it's active.

Maybe an EMP style wave animation sweeping once across the map?

Good to see the rocket headshot change. I think the same should go for any attack you don't ever aim to hit a hs with and are essentially random crits. Junkrat pipes come to mind.
