What are the most common reasons people don't dps?

[Moogly]

“Pure” healers are just as annoying and entitled as those who DPS regardless of party needs.

Thing is : you look more like someone full of himself than somebody skilled by having such a mindset. At least to me.
Where's the need of being so offensive on that matter ?
What kind of example is that to the community, especially if you're a said, good player ?
If you want to be harsh on people like in military instruction, then you have WoW...
That's where I've been trying to get to, like in previous threads.

Like, open your mind, there's not only dps that matters.
What about, I don't know, having fun only healing people ?
Yea, people can actually have fun only doing that, believe me.
Even if it's not efficient.
Even if the packs take forever to kill.
Even if you don't like it.
They're having fun.
I don't understand what is so hard about not pushing your ideals on other people.
What's so hard about accepting that other people have different expectations or purpose in playing that game ?
Have you ever thought about putting yourself in other people's shoes ?

And just fyi, I am a big fan of dps as a healer.
But when I'm not on the role, I respect other player's playstyle decision... as long as they keep me alive, which is what they're here for after all.

Also, please respect OP's wish of not being offensive to people in his thread...
