Missed attack sound

With the upcoming expansion potentially introducing a new network model, it should render the client capable of reliably determining when the player has/hasn't delivered a hit to an enemy as well as when a hit was a critical hit. I think a "Miss" sound effect would work nicely when playing with this new network model, don't you?

You could disable the Miss sound when the player is using the old network model and enable it when using the new network model.
