It's also quite frustrating when no deco drops at all on solo mode. It happened twice to me last week on Spirit of Vengeance flashpoint. Not sure if it's a bug or working as intended, but that doesnt motivate me to play this one anymore. It's not worth the time spent. Please go back to copero-nathema-corellia model where every boss drops a decoration in every mode.

I couldn't agree more! At first I thought it was just one of the many bugs the fp had. The decorations drop rate for the last 2 flashpoints must be increased.
