Run'n'Gun blessing on staff should permit quelling while sprinting

There are a variety of blessings that are more or less worthless out of the context in which they were dreamed up. What with peril slowdown and the psyker’s extremely limited stamina pool, sprinting while firing is not an especially valuable perk, in fact it’s mostly useless.

The ability to sprint while quelling with a staff would be a significant upgrade to any staff and might make this blessing less disappointing in its slot, without significantly affecting gameplay balance. Please consider this.
