Very good for absolute beginners, but "how to edit and cut away to b-roll footage like a pro." cmon, I hope that you're not serious. I like nofilmschool, but you should consider find some real pro collaborators on editing like Tony Zhou, every frame is a painting channel on youtube. This will give an edge to beginners and then they'll edit everything as a pro, not just b roll.
First of all, I'm using premiere for a film editing, and I'm very satisfied how fast and responsive it is for me. Usually it's an offline work, and for me it's fine. I agree with the most comments above but first of all I would like them to fix audio workflow, especially AAF. It's a buggy as hell, and if I want to be on the safe side I need to use omf which is centuries old.
