Druids can only start practicing large animal Wild Transformation at level 7, and how many Druids are above level 7? And of those, how many have successfully learned the Wild Form of a large animal?
On the forums, there are plenty of Druids who are level five or six and haven't even mastered the Wild Transformation of a small terrestrial animal!
After all, to learn Wild Transformation, one has to be a "Wild Man" in the wilds for a period of time. Mu Ying has a Space Ring, which makes it convenient for her outdoors, but it's much more troublesome for ordinary Druids, and it's not easy to find a suitable animal model for transformation.
Moreover, Wild Transformation is indeed very flexible, and your strength entirely depends on the animal you transform into, which makes it hard to define specifically.
Also, Mu Ying's Wild Form indeed added a lot to her defensive items, so her words weren't entirely an excuse. She just concealed the existence of the Natural Bracelet.
