I love the ad hominem, when you can’t come up with an argument.
I play this game specifically for Questing/Leveling a bunch of Characters/Classes/Professions. I literally don’t see how the OP is unable to do leveling content.
They only mention Group Content such as Dungeons. Which I can always go back and complete the Quests for those. So, I’m not seeing how difficult it is to Quest out in Azeroth
