I agree with Carter, I think that it should be down to the team how they wanna distribute the duties and good leadership in a good team would guide the team to contribute to the network like everyone else.
It would just be an annoyance to individuals rather than a force, because if others don't wanna contribute then they still don't have to even if your "outpost overhead" is high, and if you can't get your team to work together to contribute to the network then there is a problem with the team itself.
Another thing is what would happen to solo players? wouldn't that just make it awful for them?
Say if the team is contributing equally to the network but a person is just super active and takes a lot of ops from others, why should his overhead increase for simply being active and taking other ops?
