I'll never see the enjoyment of an easy carry.
Honestly I never saw the enjoyment of getting power leveled either...but I guess thats a bit different.
I don't think the enjoyment comes from the act itself. Think of it as making a choice between taking the stairs and taking the elevator.
My personal experience with power leveling is similar. I don't want to power leveled because I like the act of power leveling. It's because I am at point A in the game and I'm not having fun and I want to get to point B. I've always found power leveling extremely boring but that doesn't mean I would never do it.
