Here's a great question for you guys.
Who should pull mobs for the group if there is no dedicated pulling class - Crowd Control, DPS with aggro drop ability (Smoke bomb, FD etc.), the main tank or another option?
First, I have to stop and appreciate for just a minute how awesome a game is when there are actually pulling classes.
For a pulling class to exist, that means there must first be a mechanic which requires a group to sit back and brings mobs to it rather than faceroll through everything or 'play through' content.
Then you have to actually have a class with uniquely designed abilities that aren't homogenized across all of the other classes and "core" archetypes like healer, tank, and dps. When there's a puller class, there's also typically a CC class and a support class that isn't a healer, and chances are class variety and role filling is quite varied too.
Now to the question.
