I can see this being possible, but I can't see Blizzard implementing it. Trolls in WoW can already be druids, so having the Zandalari become druids makes sense. But for humans to suddenly become druids?It would be really weird, for sure. That's like if they said orcs can suddenly be druids, and at that point, you might as well just shrug and say anyone can be. I doubt very much that they'll do this. If anything will be another druid for Alliance, it'll be a Nelf Worgen or something.
if anything a human druid animal form would be a mountain lion for cat form, a Kermode bear for bear, a pronghorn for travel form, and a great grey owl for flight form
Why does anybody bother interacting with silverdragon? They are very clearly a troll.
Now that would be awesome!
