If you are a NEW subscriber, playing a low level character:
1. You are being forced to play the Battle for Azeroth (BfA) expansion, because that is the only way Blizz can get anyone to play it. It is most people's least enjoyable expansion.
So ha ha, the joke's on you!
2. On your zone map you will see a highlighted quest location for "A Dying World". If you are here, you've probably spent about an hour looking for the quest giver, and haven't found him. That's because he isn't there! The marker points to nothing!
Ha, ha, the joke's on you!
3. The questline for the "Heart of Azeroth" is an interesting and important part of BfA. But...you can't get the Heart of Azeroth until level 50! So you are being forced to play BfA without the most interesting part of the expansion! And, since you will drop BfA like a bad habit once you hit 50, no Heart of Azeroth for you!
Ha, ha, the joke's on you!
4. There is no way around this problem (at least that I can find). And yes, this problem is due to simply laziness on the part of Blizz. And no, there is not a single place on the internet that explains this problem. So don't feel bad if you've looked and found nothing.
So ha, ha, the joke's on you!
If anyone believes that I am wrong, or has a workaround that I haven't discovered, please let me know. And pardon my snark. Normally I LOVE wasting time hunting snipes, but apparently not today.
