"You pull, you tank" is a bad mentality

[Kolaina]

This pretty much. As a general rule, in lower content only tanks and healers can pull (expecting the healers can manage the healing). DPSs have no business pulling mobs there, and in most cases is disrespectful of the entire party.

If you want speedrun your leveling roulette as a DPS, then I suggest you play other job.

Who made this rule? Is it official? In the ToS? On the duty information screen or anywhere at all?

So not a rule then. In fact, the lower the content, the less stuff hurts. Makes it easier to keep everyone else alive
