You can enjoy the story and enjoy being a decent player who focuses on DPS. You can enjoy the story and understand that yes, you *do* have a responsibility to play at a certain level in optional/semi-optional content. That certain level is knowing your class and knowing how to dodge aoes. No one's asking for someone to be top-tier in a CT raid. Just good enough to avoid a wipe and avoid ko-ing other players because you are playing with others

The two statements can coexist - Play FFXIV if you love final fantasy games. Play FFXIV and ensure you understand that you have a responsibility to yourself and others to play on a decent/average level.
