With elite players that negate any avoidable damage and by shoving 90%+ of the healing duty onto the other healer: maybe.
When you are learning the fight (which is the time when content difficulty matters, once the boss is on farm, no one gives a hoot): yeah: no. Just: nope.
Though I don't think that I would be able to reach 3K when standing still and doing nothing but DPS, but that's probably a gear issue.
@ lily idea: sure you could do that. But it would have to be pretty meaningless or else 90% of the community can't cope, the class does not get played and DEVs go haywire. You do realize what happened to the HW Black mage, right? In case you didn't: SE does not want too much of a gap in between a skilled player and a non skilled one. That's mainly why they simplified the Enochian mechanic.
