I would start a system that rotates the packs that you revive evenly. This does seem like something that might be hard but if you develop a system that will allow you to rotate the packs that you are earning then no one in your group will be upset on the lack of packs there getting because its fair. This action c*so result in people trusting you more as a leader and maybe even join your group. The more respect you get as a leader in your server the more people will want to follow you which can help your server as a whole.

Not not read all of the responses but Qv has a good idea- Gl with your group
