I think having achievements becoming more visible in game and not just Lodestone will encourage players to do more things they normally wouldn't.

I apologize if these are already in the game:
Clear Toto-rak.
Defeat boss 1 / 2 / 3 in dungeon.
Repair 5 / 20 / 100 / 500 items.
Spend 1k / 10k / 100k on Npc repairs.
Defeated one of each common creature type.
Been raised 5 / 20 / 100 times.
Landed a killing blow on an undead using Banish.
Killed a floating eye with a spear.
Slew X hundred of creature type ¥.
Spiritbond with X number of equipment.

You can seE I got carried away, I stop now
