When a user is assigned the Approve Promotion Task, the task should have the Requested Promotion State in the Attributes. It's displayed in the email but it doesn't show up on the Attributes for the actual task. You shouldn't have to navigate from the task to find what state the object is being promoted to. I had an open ticket for this, C13801484, but doesn't seem like it's possible to add this attribute to the task page which seems weird to me. If you're approving to promote an object, the task should display that detail.
