Apart from the World Boss.
I don't see any reason to continue doing them whatsoever. Sometimes it's better to log out and do something else than find things to do just for the sake of it in order to fill your time with WoW.
Do you think I'm going to keep doing them in the hope of titan forged loot (to blizzard)? Well, no, I won't.
Stop WQ's and see how much it affects you. Guess what? It won't.
for context: I'm at 42 artifact, 884 ilevel and beginning NH heroic tonight with my guild (wahoo!)
