I agree that we don't want absolutely everything about Hive figured out, but a lot would be known over ten years of psychic investigation. Still, even though the vampires know a lot through Gabriel, that doesn't mean the citadel is as good as dead. The execution of any plan will be fraught with complications. I think one of the big ones is that is is located far enough underground that Gabriel can't reach it directly with his influence. Correct me if I'm wrong. Also, I'm sure trying to get to any power source to interrupt it is going to be very dangerous. Then the vampires have to travel down into the base. That could easily become a tomb. I'm sure you can think of more tricks and traps.
