Active workflow tasks assigned based on the role need to reassign those tasks when the person in the role changes.
When the person assigned to a role changes it is critical that the workflow tasks assigned to that role automatically update to the new person in that role. Right now we have to update all workflow tasks manually when the person in the role changes. Workflows could be so much more useful. Please make this a priority.

Some of the workflow training videos suggest assigning workflow tasks to teams instead of individual roles/users for this very reason.
