Since the OP is a DRG:

DRG was arguably one of the more simplistic of the dps jobs prior to 3.0 and those players seeking a relatively relaxed playstyle seemed to gravitate to it (that and BRD). The new skills have made DRGs just as complex as the other jobs now though so those players have lost their easy rotation. The only choice really is to keep practicing and learn how and when to use the new skills. Everyone has to do it, regardless of job, there's just a steeper learning curve for DRGs due to their previous simplicity.
