As the leading business and educational software, Microsoft should want to stay current with what educators and students need. Students NEED the MLA 8th edition to be an option in Word 2016. It's an update. Software updates happen regularly. This will impede my students doing their research papers correctly as well as my ability to teach them how to do it correctly.
