The first class I considered was the Exploration group.
https://planeshift.teamix.org/myplane/help/3It really needs one achievement for each city. We can add meta-achievements later when additional levels are added to the in-game environment.
What about the wilderness? What about dungeons? The Eagle Bronze Doors? Don't forget about zones like Shindrok's Crater.
Then, I looked at the Progression group.
https://planeshift.teamix.org/myplane/help/2Seems decent enough.
I would add some for a few of the longer “quest chains” which get you in with a few more of the major or more notable organizations. After all, these characters are all on an RP server.
Of course, this would require tagging those quests in the database first.
The final group is PlaneShift Loyal Fan.
https://planeshift.teamix.org/myplane/help/1It could probably be renamed to PlaneShift Loyalty or something. Otherwise, there isn't much I could see which would be useful here. Maybe you could add some achievements for a player's score as an Advisor.
