Sure, you can get Ferals when they shift out to CC and what-not, and, of course, resto is easily CC-able unless they got Incarnation going.
So, Druids are immune to Polymorph while in any form but Treant form.
Edit- Actually, Treant Form may also be immune to Polymorph, as Treant Form may turn the druid into an Elemental, which makes them immune to CCs that do not affect elementals. Unsure on this.
