Gentleman Cho'gath is bugged, he uses his normal ult noise.

After the latest patch, Gentleman Cho'gath no longer has his signature NOMNOMNOMNOM ultimate noise, now it's back to Cho's regular gurgly sound. He might have other broken noises too that I haven't noticed, but I'm pretty sure this is the only one. This is pretty important for those who payed for a legendary skin for that voiceover.
