What would a good “end game” look like to you?

My only real ARPG experience is D3 and D4 - and honestly, I love them both.

I hear it said…all the time…that D4 has no “real” end game. And I realize, I have no idea what anyone means when they say that.

So, if you had a magic wand, what WOULD D4’s endgame look like?
