More specifically I'm trying to understand if a Barbarian who has been polymorphed, either willingly or not would be able to rage. However this also applies to things such as Uncanny Dodge, or Evasion, anything a player might want to continue to use while no longer themselves.
Many questions specify you're able to rage while Wild Shaped, as Wild Shape specifies
You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so.
However, polymorph specifies the following,
The target's game statistics, including mental ability scores, are replaced by the statistics of the chosen beast. It retains it's alignment and personality.
The creature is limited in the actions it can perform by the nature of its new form.
Unlike Wild Shape, nowhere does polymorph specify that you retain benefits from your class or race. Does this imply that class abilities do not carry over to polymorphed individuals?
