If you loose a henchman during battle you should quickly reassess how the battle is going. Often times, the loss of even one henchman can turn the battle quickly against you and so it is better to retreat on your own terms than to be forced to retreat with a severely injured and dying party.

One of the most important things to think about, as you play with henchmen, is that you are not part of a team with a common goal. Without your direction the henchmen will hang around and do nothing about Guild Wars Gold. This means that your mentality has to be a bit different than it would be with a group of human-led characters. When playing, think of yourself as a director. Use your weapon not so much for brute damage killing, but more as a large pointer that directs the flow of the battle. As a ranger, when I play, my damage when I lead these groups is minor, my job is really to point to my target and yell charge!! (OK, I get some strange looks from the neighbors when I do this but you get the point).

With the philosophy of leader, not brute killer in mind, you should choose your skills accordingly about Guild Wars Gold. I particularly like interrupt skills because, as a human player, I know which attacks to interrupt (when target is healing itself, or about to unleash a very devastating maneuver), and which attacks can be safely ignored about Guild Wars Gold.

Obviously being able to revive fallen allies is huge, thus some sort of revival skill is a must for your skill bar. It is for this reason alone that I usually choose, as my second profession, monk. Finally, you need some skills that will keep you safe. As a ranger I usually take two to three skills that allow me to avoid being hit.
