The bestial wrath part of the equation is definitely a pvp thing for feral druids, and much, much needed. With less mana for shapeshifting to close distance on their target come WotLK, we needed some tools (actually we were already incredibly hurting in arena). So we got a tiny little snare that hopes to help compensate for the range bug, and an enraged state in which we can not be feared by hunters, priests, locks and stuff once every 3 mins or so. We needed that seriously.
For PvE we needed an oh shit button, and we got a last stand type ability. For PvE dps we needed to scale better and an adrenaline rush type thing helps on that end (though probably not as much as the changes to OoC, Savage Roar, KotJ).
And by the way, WoW isn't balanced around 1v1. And just because a feral has a very strong chance against an equal geared warrior doesn't mean ferals are overpowered. Fail.
