What are Druids supposed to be doing? They look like off-brand priests with the ability to pop a shapeshift when people get past your fighters and close you in melee range.
I'd say they're more like off-brand Wizards with a nature theme that's focused on crowd control. They have similarly terrible accuracy and deflection, plus pretty mediocre endurance and health. With then the whole transforming thing for added variety.
