so im just looking for those in fireteam that that want to complete co-op achievements and play a match now and then, not really a most active company but if you are looking for company that has no play-hour requirements and that just lets you find more people to play with then this is your company. In this company its pretty free what you want to play and you can just message members of what you want to play and if they want to be part of that game.
also if you need help with legendary playthrough i believe there is people who would want to play it in co-op too.
