95% of fireteams I attempt to join are full, even though they look open when the overlay pops up. Refresh page and it keeps the same LFGs you know are full. It also then bumps some 30m old NIghtfall LFGs to the top which are definitely dead after that time. It's easy to lose your filtering as well. Overall a very poorly implemented experience I give it a D-. Barely passing. It functions but not well at all. Design is fine (its good they moved the filter dropdown above the list), but majority of the time the experience just a never-ending "refresh-can't join" cycle. It's like the back end wants to auto-update on some slow timer, when it should be auto-updating on user activity triggers in some way.
