I only now noticed (slow me) that, aside from Y'Shaarj having a pretty scary voice in comparison to C'thun's and Yogg-Saron's voices, there's also this was there to surprise me:
"Mh.. I only sleep...".
Now I know that Blizzard said Y'shaarj is 100% keel-keel X_X-dead, but think about it.
They were asked a question about a character that was pretty new back then and there was only one thing they could say to keep it secret. Outright admitting they were going to utilize Y'shaarj would kill that secret off, and saying "We can't tell you yet" would be indirectly confirming it for people with a higher amount of brain cells than the average ant. (No offence, but "we can't tell you yet" is basically outright confirming it)
Thus, they could've gone with the safest way of answering that question and keeping their idea hush-hush.
I'm not saying this has to be the case, but just that it doesn't seem so strange to begin with. The quote "I only sleep.." only supports that idea. I mean.. he's supposed to be dead. 100% dead. How is his echo talking to us -- why is his heart still alive in a cage of sorts, and why does he talk about only sleeping?
After all, the Old God-type of sleep is what happens when their mortal husks are slain and they have to recover.
Your thoughts?
