I really wish non priests were allowed to choose a good. It is the FR/DnD, dieties are real and they matter. At best, it could add a lot to the game. Even at worst, it is just a nice part of the campaign world, and can play an important part of creating a character so having it 'officially' be part of the character sheet would be nice.
Also is pretty weird why only clerics choose it, when Faerun if you see the chronology of the setting Gods were pretty much involved with the whole story. Religion in this game can open for interesting roleplays perspectives besides clerics.
Dont know if is WoTC though given their stupid decision for Paladin not having deities attached to them anymore.
