As stated i have no created this addon... just slightly edited it too suit my own needs... this mod will play the "Finish him" wav from mortal kombat on reaching 4 combo points, and will also play "Excellent" also from mortal kombat when they are used.
I modified this add-on i was not really needing all of the other combo points sounds... as I only ever use my finisher on 4 and 5 combo points anyway...., so with this add-on playing on 4 combo points... I would let me know that i need to use my envenom... without me having to keep track of combo points on screen.
Anyway Special thanks to VgerAN for doing the hard work, and if any of you wanna try out the original unmodified version, heres the link http://wow.curse.com/downloads/wow-addons/details/hear-kitty.aspx
i take no credit for this just wanted to share my modded addon with the other rogues if they also find it useful.
