I'm ok with this, but only if they also allow role specification. A LNC or DRG in sturdy armor can be a tank in a pinch, and a THM with CNJ spells slotted can be a healer. Allow such dual-role jobs to enter dutyfinder, even if a a 50% matching preference, and they can then lot need on their selected role gear. It may also shorten the long wait times (in most cases it's the tank and heal slot that are slow to fill).
