Hey I was about to make a thread like this too. Im sitting at work bored and was thinking "im almost through the story and will be doing endgame soon. Wait do I even know what endgame is?"

At what point does "endgame" content begin and what is it? Certain level 50 dungeons?
What role do hard primals play in endgame?
Is endgame essentially farming tomestones for darklight? Or AF2?
Is it ok to begin endgame content wearing full AF1?
Am I expected to have a relic weapon?

Any responses much appreciated.
