It's not "working for your fun" that's unreal to these people. They simply grew up with more technology than you or me, they adapted to the faster lifestyle and changes happening around them. Simply put, they are used to things going a lot faster than you or me. This trend will very likely continue.
Just like 'our' generation adapts quicker and is used to faster changes and faster games than older generations (just try to explain facebook or a tablet to your parents or grandparents), the same is true for us compared to even younger generations. They adapt quicker and are used to faster games than us. It's a continuing trend.
In that sense, it's totally normal for Blizzard to create the possibility to queue for dungeons, raids or battlegrounds from anywhere. Sure, it may have been more immersive to go to the location first before you could start, but that's outdated for the current generation. They want to pick up and play, they want things to be fast paced. If things are going too slow, these people will simply find their joy somewhere else. Some of us may not like it, but it's a smart move on Blizzard's part.
So yeah, you're right that it's a generation problem. But not because the current generation doesn't know what working for fun means, they just want to see results faster. Heck, everything needs to be faster.
