I'm going to use an analogy to perhaps get the point across a bit better.


Lets say as a Boss you are hiring a janitor. His job is to clean. You pay him to clean, and nothing else.

Well, one day, he's cleaning, and he walks into a room and OH NO IT'S ON FIRE.

Here are the choices.

A: The Janitors job is to clean. He's going to clean even if it means walking through that fire to do it.
B: Call the Fire department, then resume cleaning.
C: Use his DIRTY MOP WATER(MW procs of the janitorial world) to put out the fire.

The fire isn't anything big, just a small fire probably caused by somebody throwing a cigarette into the trash can while it's lit, and then leaving.

Which one do you think is the smartest.

A is what you are proposing. A dps's job is to DPs, and nothing more. If he does something other than DPS, he deserves to lose his "job".

B is the equivalent of calling for a heal. Ideally the "fire department" would be able to come and fix the problem.

C. Is the smartest option. Sure, the Janitor is wasting his mop water, but he's doing it for a good cause. Sure he could have called the fire department, but he saved everybody alot of time, and you a lot of money, by doing it himself.
