So here is my story. I was running WoD this week, when the drop that I had been waiting weeks for appeared. At this time my inventory was full, so I was unable to roll. But here is the thing, what displays in the UI when your inventory is full is exactly the same as when you have already rolled on a weekly lockout, and as the previous week I had gotten my drop late on the last day, I thought I had accidentally gotten my drop already. Because of this, I was annoyed and clicked pass instead of cleaning my inventory, which I would have done if I had realised the real reason as to why I could not roll.
What I ask for is that the UI be cleaned up so that this confusion doesn't happen. It's a simple fix; If your inventory is full, it should not grey out Need/Greed, instead it would allow you to roll, but give a popup telling you that your inventory is full before it allows the roll to go through. I feel this would be a much cleaner system, and would prevent confusion in the future
