We see worgen druids of the claw disgusing themselves as bears in Silverpine which is able to fool some of the ranks of the forsaken army, much to Sylvanas’ anger.
Similarly, it’s speculated that harvest witches can take a flight form, as Greymane apparently finds simularities between a night elf changing from bird to humanoid and the harvest witches of Gilneas in the short story ‘Lord of his pack’, although I’ve not personally read the story so if anyone who has can confirm this, it would be greatly appreciated.
What I can say fairly definitively is that the worgen curse has it’s basis in druidism. Worgen exist in the modern era of WoW due to night elves far in the past attempting to make use of Goldrinn’s pack form, and failing to overcome the rage of the wolf god, resulting in twisted, half-humanoid wolf monsters that eventually get banished into the realm of the Emerald Dream, only to later be unleashed into Azeroth by Archmage Arugal.
Because the curse has it’s nature in the dream, I think it can be argued that worgen have a natural affinity towards druidism where other races might not so much, meaning if they want to pledge themselves to Aviana and become a Talon, or Ursoc/Ursol and become a Claw, or simply continue down the route of Goldrinn worship and fanaticism, then all are viable paths for a worgen to take.
Although I’d take all of what I just said with a grain of salt, I’m fairly confident on all of these, but if anyone wishes to correct anything I’ve said then by all means please do so.
Regarding harvest witches, a friend of mine sent me this community developer quote from 2013.
What is the lore behind Gilnean druidism and the existence of “harvest-witches”? Is it a native practice, developed by the humans? Did they somehow pick it up from the night elves, even before the Eastern Kingdoms’ discovery of Kalimdor?
In the early days of humanity and its civilization, many tribes of humans had primitive belief systems that incorporated simple nature magic. However, the rise of organized religion such as the Holy Light and the potent arcane magics introduced by the high elves quickly supplanted such traditions. Gilneas, due to its relative isolation, has retained a degree of their ancient culture in the contemporary era. The religious leaders of what was in Gilneas referred to as the “old ways” eventually became “harvest-witches”; those who used their nature powers to augment Gilneas’ agricultural output during and following its period of industrialization. Due to the presence of harvest-witches in their culture, when Gilneans learned about night elf druids (albeit through second, third and even fourth-hand sources) they became fascinated by them and their exotic connotations, to the point where many started referring to harvest witches as “druids”, though this was quite far from the truth, as few Gilneans had any idea what a druid actually was! Harvest-witches have a limited control over nature, especially plant life, and the powers of harvest witches bear a coincidental resemblance to the low-level abilities of actual druids. Harvest witches who contracted the worgen curse (which was druidic in origin) found that their powers were somewhat amplified, and after making first contact with the night elves cursed harvest witches were offered induction into the Cenarion Circle for both study and training.
