The fact that you can't just press a button once every 60 seconds and enjoy their full benefit is what makes them good talents, but we've had this discussion repeatedly and I'm not going to bother having it again.
I already know how fond you are of rotations where you press a button once every 3 minutes rather than do something yourself
I'm also slightly confused by the repeated requests to make RoP instant... you are aware that the cast time is already one GCD right?
You can avoid any DPS lost at all by casting it before you move, and if that's not possible you lose a massive one GCD when you arrive (which you'd lose anyway if it was instant and appeared at your feet, and which would be an insignificant gain if it was instant and you could cast it while moving).
