Marketplace Download Data stored in hidden folder location

Weighing in as a user with plenty of space on my C drive: this is, quite frankly, offensive.  My game is parked at the January 13 patch anyway (because R&L patches borked so many essential functions), but this is all the more reason to never update.  I wouldn't interface with the Marketplace at all under these circumstances.  Thank you Crinrict for the important PSA!  It needs to be more widely broadcast so people know what they're getting into.
