I always thought that the guardians were supposed to give an indefinite buff to your character depending on the guardian chosen. After playing since alpha of course I know that's not the case. I would definitely like to see the guardians have a good role in gameplay, such like you say Perrin. There aren't any 2-hour abilities like FFXI had, so why not make a guardian buff the 2-hour? Sounds like the perfect idea to me honestly.
