A couple of questions:
Is the target moving?
Do you need to run out to avoid damage?
Do you rely on counters who will tick out if you take breaks in dpsing?
Invuls?
Are you supposed to avoid taking aggro?
Any reliancy on other classes/buffs?
Are you supposed to aggroswap?
These questions and many more influence the answer to the OP's question.
