Honestly I am sick and tired of people telling others how they 100% have to play, when they don't pay for their subscription. This is why hardcore players are frowns upon, because they act like totalitarians to various play styles. Just worry about yourself, and stop telling others what they have to do. If a healer wants to DPS, great. If not? Well at least you're alive. Worry about yourself. Content doesn't usually last anymore than thirty minutes.
