Make the charm pulse usable when running but make it an interruptible cast (not insta). Many self buff spells on Live work like this. You can cast them while running but they are still interruptible.
This way the Minstrel can't hold a charm if he keeps getting hit in combat. His pet will turn on him. If the Minstrel is able to free cast he can get his pet back (by mezzing etc. then getting a few seconds to re-charm.)
