I've completed the raid over 50 times and have a 318 ghost as my best. I've also played iron banner and got nothing. I'm happy to get the 320 Crimson shell. But I agree that the raid drops suck. Count yourself lucky you have two. Out of my regular raid group who completed with me every week since day one of the raid only one of us got a 320 and only once. Rng sucks.
