Feel like you have to convince players sometimes to even try winning, not even about tactics. And yeah everything you say will be read after 1-2min, so keep that in mind when trying to lead your group. In JP they pick 1 commander and that was it, he will say he is the commander for the round at the start of the match, and everybody agrees to that. Their gameplay is a bit more predetermined and a bit static, but more coordinated. In Guild Wars 2 you could buy a special symbol(marking) for PvP so they would recognize you as a leader, could be helpful here too.
