LF BRD : a solid opener + rotation

[Mature]

So i decided to take a break from SMN for a while and I've been testing my Brd rotations with the a12s dummy. I can break the dummy with 12-16 seconds left on the clock (ilvl 269) i feel way behind everyone else (with my SMN I can break it with 46 secs left) . I must be missing something somewhere. When watching a video to compare is o difficult to follow a brd rotation cause RNG (blood letter procs etc)

Could someone be kind enough to help with a good opener and first phase rotation?

Thanks x
