IMO the bad rap UML gets is undeserved. The value of a detailed design in UML may be limited. But high level design elements like use case diagrams, sequence diagrams, activity diagrams - these are super useful.

Simpler "boxes and arrow diagrams" are fine but it's nice to have some consistency in the visual representation of these elements.
