For this suggestion I am only focusing on Bounty Hunting assignments since they are the most popular and group oriented.

Currently I don’t see a good reason to form squads for Bounty Hunting Assignments since each person still has to kill the targets themselves.  The amount of rep you get for accepting a squad assignment is pitiful when you still have to get the kills yourself.

So I would suggest either increasing the amount of rep you get proportional to the number of squad mates.  I am not suggesting it be as much as you would get alone but something that gives an incentive to run assignments as squads.

My second suggestion, which should be easier to implement, is to give everyone in the squad credit for kills.
