I'd prefer a quest that tests your abilities.

"Use the Duty Finder as a tank role to enter a level 60 dungeon and do not lose enmity once 0/10"
"Use Sea, Stone, Sky as any DPS class and complete Midas Fist of the Son (Savage)"
"Enter Solo Duty where you need to keep every NPC alive during waves of attacks" - includes non-healing things such as ensuring debuffs are gone. DPSing can help speed it up, but isn't necessary to complete. Must be able to manage MP

All of this would take a few hours, anyone could do it, and you'd only get people who have all 3 roles at 60 + be semi-competent with each.
