No MATE love?
I'm a bit surprised that the option to install the MATE desktop wasn't mentioned in the review at all. The first thing I did when running Fedora 22 in a VM was:
dnf groupinstall "MATE Desktop"
Logout and then when you select your user from the login screen, click on the non-obvious gear icon and select MATE as your default login. Your login should now give you a GNOME 2 look-and-feel which for us die-hard users is, just, well, better.
Mind you, if you're not a fan of Fedora's lunatic 6 month update cycle (this is not and never has been a good update interval for any OS ever - I'm looking at you, Ubuntu, too) and the need to upgrade every 2 releases, I'll point you to CentOS 7, which has 10 years of support and once you enable the EPEL repo, also has the option of the MATE Desktop.
