Druid Cat form changes in 1.7

[Gurnsey]

    * The global cooldown on Tiger's Fury has been replaced with a one-second self cooldown. Its duration has been increased to six seconds.

This is more significant a change than I think most people realize. With a little attention, the fact that it doesn't trigger the global cooldown means that it works out to a constant +40 dps at a cost of 30 energy every 6 seconds, or effectively, a +40dps buff that reduces your energy regain to 50% of normal. Not too bad especially for long fights, and the consistency means that you won't pull aggro on a series of lucky crits (or at least are less likely to). It doesn't eat energy as fast as you regain it, so you even have enough to use other skills while this is up (better now cause it doesn't trigger the global cooldown)!

Keep in mind that this is only from my experience messing around with my wife's druid. Your results may vary.
