Id argue that this has more to do with the type of content rather than making groups.
Cataclysm classic had group finder and that was a misrerable experience too.
Why? Because Cata heroics have massive fuckup potential.
Vanilla dungeons also have massive fuckup potential. They are technically way way easier but you can ruin a run really fast by not dismissing a pet or whatever and then it takes ages to recover because you have to ghost walk through half of the world and some party retard cant find the way back in.
