I don't suggest a feral use a healing weapon. Thats moronic. But druids as a whole have plenty of legendaries to chose from. Much like rogues. There are three that we could use, but are all pointless for the majority of the rogues cause of daggers. and all are pointless other then vanity now at this point.
Fact is, Blizzard isn't going to make legendaries for niche roles. Dagger rogues, ferals, and anything for dps shammys. I am actually pretty surprised we haven't seen anything for tanks yet, but I think Blizzard made a comment about that at last Blizcon about tanking stuff not being as exciting. I can't really remember though.
But yah, we'll be getting more 2/1H swords, more staffs, or more another kind of weapon that most classes can benefit from cause Blizzard doesn't want to give just a small % at the chance of a release legendary. They want a lot of classes to be able to use it.
