How scared should I be about DPS?

[Shurrikhan]

When you end up with phrasing as ambiguous there is sure something wrong with how you see the game. To me there's two only moment I can't DPS : I'm dead or the boss is impossible to target. Outside of this, I can just press that Stone IV/Broil II/Malefic II all I want.
More likely it's from "when can I DPS ?" to "how much do I have to heal ?" that will land you better success. Healing isn't just casting, all classes have a lot of OGCD now so it isn't really strictly about casting heals vs casting DPS. Planning ahead is much more important than landing two more cast, wich is only a matter when you know the fight perfectly and try to get a better performance.

And all this vary depending and the other healer. No only depending their performance but more simply with how they use their CD.

I meant to imply quite heavily that those were the same thing. How much do I have to (do something other than DPS) --> How much do I have to heal? I should have done another pass over for semantics.

Thank you for the reminder. I've reworded for precision while trying to maintain brevity.
