How do you Shape shift as druid?

Answer 1

Starting at level 6, druids will receive spells that allow them to turn into one of several different forms. To shape shift, all you have to do is to press the button on the special bar that has all your forms on it. You receive your forms at different levels and talents.

For instance, all druids can turn into a bear (tank), cat (feral dps), cheetah (travel form), sea lion (aquatic travel form), and bird (flying mount). These forms you will receive when you reach the appropriate level. Moonkin form is the balance (ranged, magical dps) form you receive when you take enough points into the balance tree. Same with tree of life form (healer) in the restoration tree.
