Doesn't sound like it to me. Looks like you've got an angle to try and prove this wouldn't be a new class, even though no one has said that it would in the first place.
Having just read the entire thread looking for any reply on this being made into a class... You are the closest one bringing that to the conversation. The response you got from Teriz was that Blizzard _could_ make it into a class, not that they ever _would_.
Like I said previously, no one has made that claim in this thread, so I'm not sure what your response even means here.
