Any place where you have repetitive actions based on field values.
For example, say you have a Document Type field that says "Invoice", "Purchase Order", etc. and you route these documents to a folder corresponding to the type: \Some Path\Invoices, \Same Path as before\Purchase Orders, etc. In that case a single Route to Folder activity using the field token ("\Some Path\%(Fields.[Document Type])s") would eliminate the need for "if invoice, route to invoices folder"-type branches.
The same would apply if you want to send a document to a user that is picked by the workflow initiator through a field value in the Laserfiche Client.
