Yes, I have been wanting to re-enable those extra skins but there was a problem where sometimes the team colors would be wrong for the Skaarj and possibly it was an issue for the warcow too. I looked into this a little bit recently and I think there is a fix for the warcow but the fix that is available for the skaarj didn't fix this problem when I used to have those skins enabled on the server. I will check into this more soon and perhaps make a new fix, if required, to solve the issue.
Originally, I didn't add the "revenge" sound because some players get caught up in seeking revenge instead of actually playing the game and I didn't really want to encourage this but if it is something others would really like to have I can add this.
Does anyone else want the revenge sound?
