Don't know if the is a specific thread already, but for this let's keep it simple. What should be added to help keep the content alive for later on, as well as add interest but not remove the grind. Since the grind once done never has to be done again to me seems fine, but a level synch option along with some simple mini quests like defeat x fate.or monsters to give a small xp boost or even basic survey missions would add flavour, say 3 per day like beast tribes.
