I am similar to you, I played 2.x as Bard up to right before 3rd Coil was released, then took a loooooooong break for IRL reasons. I'm back on a new account now and re-learning Bard. From what I have gathered and researched, 4.0 Bard, outside of your opener, is less of a set "rotation" and more of a priority system of making certain things are constantly up and weaving in your other skills as they fit into cooldowns.
