First MMO I'm guessing. No worries, once you figure out how to play your class (which skills to use in what order and in which situations, which to save, and which to use non-stop, etc), and learn how fight bosses (watching for AOEs, interupts, knockbacks, adds, etc) things will get easier. Don't be a complainer though, when you get beat figure out why and then go back with a new strategy. Adapt and survive!
