About that "mega uber customization overhaul" to the customization system Saber talked about sometime ago, I hope that they are taking cues from some of the guys on their forums. By God, these are leaps and bounds better ideas that we got in the base game.
Something like this would be a gargantuan improvement:

They've had all this time prior to the premiere and yet they still failed to deliver a good customization system. We've had to wait months before colorable lenses were added, not to mention dyable cloth. GW or not, in a game where you can create your personal Astartes you should have as much control over most details.
