From the (enter profession here) base you will receive:
Profession specific missions
Profession specific armor and weapons
More Detail
Each profession has a “League” or something to that effect. Located in LA periodically or maybe even daily you would be able to go to the base they are set up in and get a mission. Like a personal bounty hunt. Maybe people from around Tyria ask the leagues to provide assistance to them around the world and these assignments are divvied out to you from the leader of your profession league.
In addition you can get profession specific gear at different level tiers (20, 40, 80). This all would set you apart as the profession you are and make it feel like it makes a difference. Something SIMILAR should be done with the Vigil etc.
