It would be nice to have the Quake kill feed sound effects added to the server. It's a neat thing and also adds a sense morale boost to one. And I'm assured anybody would enjoy seeing their name across the screen saying: X is dominating". And also hearing the sound effect play. There's also a female version of the sound effects. I play on a Day of Defeat Source and they have the female one. It's rather enjoyful to get a killing streak going and hearing the sound effects go.
I believe it'd be a nice addition.
