Looking through what could make a mesmer more wanted in PVE groups, why not a Fear hex?
Fear {Elite}
For 1..5 seconds, you have 20..80% chance of inflicting fear into target foe.
Attribute: Fast Casting
Energy: 5
Cast: 1s
Recharge: 5s
This hex would make target foe flee from battle, much like the flee effect when mobs flee from an AoE effect. It would have no effect against bosses and PvP players. This would add a new role to mesmers, possible making them more wanted in PVE groups.
It would also be easy to implement the skill ingame, since it would make use of the existing fear effect already present ingame. Probably a 5 minute job for the dev team.
