If you have a healer standing there doing nothing, you fail as a tank. Pull more. If all they want to do is heal, then give them a reason to do it. :P

Seriously though, I don't care if the healer doesn't want to DPS. The general tactic these days is to pull everything you can handle and AoE. I always ask the healer what kind of pulls they would like and act accordingly. I have yet to see one healer say they want smaller pulls and then sit there. When I heal, I tell the tanks to pull it like they mean it. So it seems to me that the solution is to give the healer something to do. Even if it means pulling more mobs so they start ABC'ing on GCD.

When I am on healer, I personally love to DPS. Some people might not remember but stance dancing was challenging and fun. The fact that it's now gone makes me happy, because DPS just became that much easier.

One thing I find funny, is that some people in here are trying to compare derp finder and savage.

Also, MP management can get real if you try to over dps on SCH. That cost of Miasma III (or is it II, I don't remember, it's the instant AoE) chews up MP real quick if you tunnel vision.
