Certainly for GB riders. Has the potential to make it a bit more exciting though. In a three way fight between Nibali, Contador and Froome, the risk would be that the first two would go head to head. Froome has both of them pegged when it comes to the TT so the other two would have had to try and manoeuvre the other into being stranded on the other side of him. Froome then left unchecked would have had his pick of the tactical moments.
Nibali's got my vote but this could come down to the wire.
