Some of you make it sound as if healers only have one choice: heal, or dps.
That's not the case at all. I main white mage, and I dps (and I'm not an elitist/hardcore/raid player either).
I wrote this in another thread, and I'll write it again. Even when I dps, I never truly stop healing. Even as I dps, I keep an eye on my team's health bars, and I make sure to reapply regen when it's needed, things like that.
That's what a healer does. It's not as simple as "I'm only going to heal" or "I'm only going to dps".
It's a balancing act. Knowing how to set up with your tools, like regen and asylum, how to time your cleric stance and dps, switch back and get the tank up right away with benediction/tetragrammaton and reapply regen, and activate cleric stance and start dpsing again isn't an elitist style of playing. It's knowing how to take advantage of the tools given to you.
And as I wrote before, there will be times when you cannot dps. Sometimes you have to heal through unavoidable damage, heal someone who got hit, etc.
It would be unreasonable to pressure a healer to dps during these kinds of situations, but that's not what we're talking about. Nobody's saying, "dps always no matter what". That's completely unreasonable, and if people are giving you flack for not dpsing during these kinds of situations, then they're in the wrong.
But those kinds of situations are uncommon. Most of the content allows you to dps safely because the damage is scripted and relatively low.
During these kinds of times, when damage is low and tank can handle it, dps. It'll help kill mobs faster and in turn reduce the damage the tank is taking.
Just because it isn't your "main job" to dps doesn't mean you can't take full advantage of what your job is capable of. It'll make you a stronger, more efficient player. Yes, it takes practice and effort, but once you get it down to a tee, it will help tremendously.
Don't get caught up with the whole "well, dps need to do their job". This isn't about comparing yourself against others. This is about improving yourself, and becoming a better player than the one you were before.
