Being a group leader myself, it's a bit hard to find some of those spoken qualities when the server is nearly drained of players, and your own group is losing people. Not too long ago I was given the role of leader as my prior leader quit the group to join another on accord of what we all assumed was greed. Nonetheless even with my feeble amount of people in my group, I try my best to be interactive, help them with things like TI, Wanted Missions, giving them support during convoy missions, ect.
The group has gotten better over the course of a week or so, more so since we managed to beat the group that basically stole our former members in GNW when they have larger number. I managed to outplay them when it game to group formations. It seemed to make them all hype about staying in the group, and I rewarded them graciously.
