DPSing as a healer

[mp-please]

Healer DPS can be up to a third of the total party DPS in an average DF party, and in my experience often even more. That is usually about a 40-50% increase in DPS overall. So yes, it can (and often will) absolutely make a 10 minute impact on a run.

Looking at a parse right now with a total dps of 2200, party took 23mins to clear. You need a 3500-4000 dps party to clear it under 17mins, so no it won't be 10 mins by a long shot.
You can usually expect from the average DF run 400 dps from the tank, 1k from each dps and another 1k from the healer. With a competent party you'll be seeing 800 ish from tank, 1.5k~1.8k from each dps and still 1k from the healer.
The latter (5k) are the usual ones who get 15 min runs in the current experts, average of 3.5k take roughly 18mins, 2.5k go around 25 mins.

So no, it's not 10 mins. It helps but let's not exaggerate.

Err, what? I think we're playing different games, because that's patently wrong.

Single target is better if you have 3 or less mobs, at least for whm. It's more mp effective in the long run and provides the same dps due to mp restrictions. Yes i know well there are a few pulls with 3+ and that's why i said almost.
