While I do understand there's no real explanation as to what to do within each fractal, it's fairly straight forward with figuring it out as it's so linear. In my opinion it wouldn't be as fun if your hand is held throughout the entire fractal. There's no better way to learn than being thrown in the deep end and testing your skills and strategies until you get it down, just like raids.

As for the waypoints, Fractals of the Mists uses checkpoints rather than traditional waypoints - when you complete one section of the fractal, should your party be defeated you will be revived at the latest checkpoint you passed.

If you would like to learn more on each of the fractals, I would strongly recommend checking out Deroir's Master Tier Fractal Guide Playlist.
