It is really hard to assemble a fireteam ingame to do daily, weekly and raid missions. That is because we don't know what they have done yet. My suggestion is to show icons or badges in the quick inspection (when you "mouseover" a friend in the roster menu), icons/badges that allow us to know what they have done already. This would make fireteam assembling really faster ingame. I think this is a small upgrade (I know it demands a lot of work thought) that could make a big difference, it would be a great gift to the community. Thank you!
