Dont want to be pessimist around here ... we have people for that allready.

But im affraid we dont get any "style for Druids" at all. :-/
So far (including datamined content) it seems like only starting gear (and only for some classes so far) will include some class style ... and after that one will be replaced by something
harder/better/faster ... we shall wear that armor, no matter who will put it on.
I mean sure, there is some possibility that "some" armor will be fitting better to druid than to rogue for example ...
But i would not bet on that. :-/
