The tips "As <role>, I want <goal/desire> so that <benefit>." comes from Alexia Bowers.
Her article on the COP here "Idea for tension description format from agile software development"
From my perspective, this tip is inspiring as it supports the tension holder to express the motion from the actual situation to the ideal situation, the benefit for the circle and the role s/he is speaking from.
Furthermore, it supports the practitioner in this Holacracy Habit: schifting from "a complaining" stance to a "try to solve/process " stance.
