With the new changes to abilities druids can use prowl, stampede, etc, and it will shift you to the respective form. Most of these abilities aren't on the GCD so you can use them if you are stuck in a global to avoid the poly. However these are all on long cooldowns or require you to be out of combat and you really don't want to use them to avoid getting polyed.
However, Growl shifts you straight into bear form, is off the GCD, and has an 8 second CD.
Never get polyed because of GCD again!
