Request the ability to Hide the "Assign this Issue" function under "Operations".
This forces the users to use the "Available workflow actions" and not assign an issue outside the workflow.
This is really causing a problem for our team especially since we have many new users.
For example, a ticket is in QA and a business user who reported it and watching it will assign it to a business person to sign off. It is still in a QA status and the business person cannot do anything with it as they have no Available Workflow actions.
