For any Feral Druid, this talent is made entirely of Win and Awesome. For PvP and solo PvE, it rocks. It will allow you to just stay in Catform between fights, moving quickly from mob to mob. It will increase your killspeed significantly, simply by reducing the time it takes for you to run between fights. Hell, since getting it I have yet to use Travelform. If I just have to run from a mob, I use this due to the lower chance of being dazed.
It also helps you to finish off those runners before they get to their friends.
