Ya but then again Packform isn't a normal shape shift it has the raw power and ferocity of Goldrinn itself, not even Malfurian could control it. That why he banned its use.
Don't get me wrong the Worgen curse has draw backs like needing the ritual if you want your sanity and the fact you can only pass it on through the bite, but i mean it let 2 druids slaughter and entire Satyr warband.
