Maybe right after they nerfed MS for the umpteenth time and buffed the Slam talent, but if so it didn't last long.
No matter which way you cut it, abilities that don't interact with one another leads to crappy design. One of the most common complaints with Ret Paladins, despite having one of the best proc game play systems in the game, is that their abilities don't feel different enough because they all did about the same amount of damage and few did anything appreciably different from the others.
