I really don't think that it will be *that* permacamped.
I think that it might be pretty permacamped for about two weeks maybe three. Then it will turn into a nice place for people to fight over T6 loot.
Not every zone is going to be a nice little guild instance that you never have to fight for. Come on guys where's the sense of competition? It's not like some T8 guild is going to come mow you down just to steal some T6 loot... If you are obviously mobilized to take something down, I'd like to think that most (if not all) of the players on THF are mature enough to let you have your shot.
Don't ruin a good thing (in this case a contested T6+ zone) just because you can't be mature enough to sleep at night.
EDIT: double negative =P
