Another option for endgame is to just open up your achievement panel, and start working through them. once you hit 80, its totally up to you at the pace you work at. I would only warn you to NOT farm for a legendary of any kind immediately, that will burn you out the instant you make the item. some things you can only work on during the various festivals, but otherwise everything can be done at any time, and if you are having trouble finding others to do meta events with you, alot of people tend to do them at the daily reset.
