Actually everything you list might be useful in the expansion.
For the 'player who has everything' though, Turbine has a challenge trying to list a reward that is useful to you and the other 95% of the player population.
I'm sure if they included +3 BTC tomes, there would still be a tiny segment of the population that wouldn't find those useful.
I don't understand why the rest shrines can't be used in raids though. It seems like this would be something that even the 'player who has everything and only runs raids' could find useful. Is it a game mechanic or just an arbitrary choice by Turbine that imposes this restriction?
