[Resolved] PTR client downloader missing?

I downloaded what was supposed to be the PTR client setup file. Instead, it only does an update check followed by bringing up the Live launcher. Opening up WoW to double-check things, I did not see the PTR icon in the corner nor was there any "WOW1" or "WOW2" option.

Going through the whole process again -- Account > Public Test Realm > Download Game Client > Run file -- resulted in the same outcome. I asked around, and others told me they came to the same conclusion: It's been removed.
