As one example of many of a fundamental use-case that's broken... Permission group to Edit rights on a doc or folder, then add user to that group - the new user does not automatically inherit those permissions. Doc/folder needs to have the group's permissions modified manually to accept any group membership changes. I ultimately automated this with a GAM script, but it's absolutely insane that I had to do this. Aside from that, for a small company, I miss having a single common directory tree with an organized collection of company documents. With Google Drive, everyone's view is different and documents are lost when someone leaves.
