Honestly, the ribbon wasn't too bad. Was was missing was letting the user know that alt was available and usable. If the guidelines were followed as they are in office and explorer, pressing alt puts the quick access letter next to all the available items. What has really killed discoverability, are "over to show" buttons, and the hamburger. Both attempts to save screen space and present a "clean" albeit abridged view of what a user could do from an interface at a glance.
