Yes, iCloud Drive is included in the wipe. What I meant it, since I had nothing in iCloud Drive, I was scared I lost everything because all of my apps would say I don't have any file on iCloud. But then I found out that going on icloud.com you can get your previous files from there, at least from the iWork suite. So to diminish my stress, I downloaded everything and put it into iCloud Drive and thought I was set, but then the news came.
The cowboy side of me made it so I don't have a backup plan to go back to Mavericks, but I downloaded every file on iCloud and put it somewhere else on my HD just in case. I'm definitely ready for the wipe.
