It’s going to be a real chore once most players have finished the content and returned to their preferred game areas/modes.
Ding ding ding, we have a winner. 
That is why I’m honestly surprised the developers did what they did in Heart of Thorns.
As it stands now, I have zero interest in doing pretty much anything in the new areas. Can I get by? Yes. Is it even a little bit fun getting my rear continually handed to me? Nope. Ah well, I have plenty of alts. I’ll probably spend more time on them. Or maybe work on map completion in older areas, since I haven’t been playing the game that long and still don’t have that done. But after that, if things are still this completely un-fun in HoT (from my perspective) I may have to explore other games.
