This is a great talent. Shadow Word: Pain is our best damage spell, and the best DoT in the game. It's instacast, meaning it can be cast on the run, is improved by shadow damage talents, and is very mana efficient. Increasing its length only makes sense. There is a common misconception about this talent, that it actually reduces the damage per tick by extending the duration. This is not the case. You get two more damage iterations for the same mana cost by maxing this talent. The damage per tick stays the same. You will notice a difference - it won't run out before the end of a battle if you have this talent.
