So I've been playing my Blood Angels army under the new Sixth Edition rules and was discussing the way I use my Stormraven with a buddy after a game. I was telling him that with the way that they changed the rules for Power of the Machine Spirit I couldn't do my old trick of constantly turbo boosting To get a 4+ cover save while using PotMS to fire on gun. He pointed out that the Blood Angels FAQ says that the Stormraven can use PotMS to fire one gun while going flat out.
So does the FAQ override the BRB rules on PotMS?
