I enjoy talking legendaries and exotics. It's a good way to figure out what's the best way to play. Listen to other people's opinions or their "best ways to play". it's part bragging but it isn't just that its also informational.
Hunters are not useless you can do alot with invis. invis saves your life and team mates it can also be used to block teleports. gold gun is a good way to ease pressure by taking out minotaurs and Pretorians and other tanky enemies.
