Feral Druid PotP talent question

Hello there.
Going through discussions on forum about feral druid i still find one particular topic unanswered.
-Some say that Protector of the Pack increase atp overall + gives damage reduction while in Bear Form as addition
-Some say that Protector of the Pack increase atp and give damage reduction ONLY when you are in Bear Form.

Which one is correct?

Thank You in forward.

it increases only Bear Form Attack Power.
Btw it requires 5 sec to test it by your own....

Normaly i would calculate by my own,but i don't have computer with WoW at the moment,so i do calculations and reading while i wait to get back home. Cheers for help
