werebear 3d structure and the shape was not like the normal or fantasy forms of bear that were coming out before legion.
you see the reason that people are so interested in base forms of werebear was because of their new form and animation and the way that the color of their claws and skin is matched with the color of their spells . ( i mean effects.)
look at me for example why i never use my mage tower skeens or fantasy ones that are blue or green or whatever and i go with the simple one? its because the very reason that i explained. (mage tower form is infused with fell energy and druids has no fell in them not even in the effects)
now imagine people that are like me seeeing the base forms of werebear for the first time/ it was legendary just to look at those cute meow meow werebears without any fantasy effects. 
i hope i explained my point
