(Official) restricted or banned lists are only relevant for tournament play. You won't see a restricted or banned list until in an official tournament it becomes obvious to everyone present that a card is broken or so powerful that it unbalances the meta.
For casual play, players should feel free to create their own list of restricted and banned cards that they stick to when playing (or invent any number of houserules to make the game the most fun for their tastes).
We already have tournament-only rules in the game, despite the lack of any tournaments. The 50 card deck minimum is a tournament only rule. If the designers think that something is unbalanced they can issue a restricted list, even in the absence of a tournament scene.
@Glaurung - You can see a discussion of Nate's interview here http://boardgamegeek.com/thread/707056/nate-french-on-theonering-net. He says that the game doesn't need one yet, but a restricted list is an option if he feels the need arise.
@silverhand77 - Sorry if i was over seneative and took comments personally when you did not intend them. My bad. I need to develop Glaurung's thick skin. When thinking about card design, I was talking more about how it affect subsequent encoutner decks, rather than player cards (though that could be an issue as well)
