I have found myself having to take that role (for the seeming lack of other people to do so) a few times in the past, with rather varying success, so I thought I'd rather ask the more experienced people. I'm not speaking of clan/team games here, only public servers where team coordination is at best weak, and more often nonexistent. What is the best way to use the commander class in such situation? Front-line fighting capping objectives, or hanging back and using binoculars to oversee the field of battle and supply information to the rest of the team? And how is artillery best used? (remember, very little coordination!)
