i think the idea of a werewolf form is kinda cool but like the idea of turning into a dragon, it just doesnt fit in with the lore of the druids.
I think, if blizzard are going to give characters the ability to turn into dragons then it will be an entirely new class. Im guessin this because i only just finished the WoW manga's and it could be done.
On the basis of a new form though, im saying that Resto and Balnced wont get a new or improved form and im guessing that everyone will get a new form and feral will probably get an upgrade on cat form or an entirely new melee form.
