I try not to "boss" the teams I lead. Few people enjoy being told what to do, especially in a game. I am already picking the missions and setting the difficulty and pace, that's enough control.
However, I like to see organic teamwork emerge from the chaos, and chaos there is. I set difficulty at whatever level the team can handle with only occasional deaths. Sometimes that's +4, sometimes it's down to +0. If we're handling groups, I herd them using teleport. I teleport forward to a group, fireball them, teleport back, hide behind something or around a corner to block line of sight to bring them in. While I am doing that, I watch my team. As a kin, I have tools to fix some mezz issues, do some close combat heals, replenish stamina, and keep speed boost and damage buffs topped off. I have support hybrid, and pick when I activate that to support the team while the herd arrives and I shed aggro onto our anchors. I watch the team carefully and either join the fight with my own dps or, if we're handling it easily, fetch another herd. That's a judgment call that requires knowing how the team is doing, so I monitor health/stamina bars and buff lists carefully, as well as need to keep situational awareness of the map we're on. I'll sometimes quickly recon forward to identify where future herds are. I also keep track of who is our main tank/anchor, or at least, solidly filling that role, and I will use fold space to tighten the kill cluster onto them.
If the team is good, they'll see and understand what I'm doing and work with it. In those cases it becomes a real joy. The anchors finding great locations for us to establish our AOE kill zones at, with places for me to quickly break LoS, and with safe zones behind us when lowbies need a quick breather. And if they don't, well, that's fun too in another way -- comedy.
But it all requires knowing and being aware of my teammates' abilities, status, and locations.
