The following things would be cooler with a custom kill animation thing (I forgot the word): Chamber's Tour De Force, Jett's Blade Storm, Raze's Showstopper...

But the most egregious omission? The Arcane Sheriff. I am STILL pissed such a limited time cosmetic didn't get a unique kill sound on par with other premium guns.

(Side note: the entire G.U.N line shoulda got this too and had a finisher where a U.F.O. abducts the last player or something)

Dammit Riot. You have all these fancy skins and ults that kill. Give me sounds as satisfying as the Reaver line or something man!
