Consider the Light Order. Remember when Mathilde wanted a Light Wizard for the Sylvanian Campaign? She was a Journeyman, and she grabbed another Journeyman by the ear and told him to pass on a message, ended up with Jovi Sunscryer because he heard about it and was interested. When she wanted someone for the Karag Dum Expedition, she was a Lady Magister of some repute and she got to speak to the Magister Patriarch himself, who sent his personal troubleshooter. This is not because Karag Dum is a higher priority to the Light Order than Sylvania, it is because being important means you get heard, and not being important often means you don't. This is by design. Important people get privileges because it's important people that decide who gets privileges, and they decided they're the ones that get them.
