Is dpsing and a healer becoming the standard norm!

[Noxifer]

The only reason why healers have the ability to DPS is so they are able to solo content, not to deal DPS in party's.

I'll just begin by responding with this, like other people have before me:

One more time!

In other words, SE does intend for healers to be able to do some DPS in parties. (They also tell you to stop DPSing if the people in your party need healing.) So no, like you say it's not the primary task for healers, but it is part of their toolset. To not use that toolset because "it's not my job", is like a Monk saying, "Well, I only need to keep myself alive during solo content; in parties that's the healer's job. So I'm not going to use my Second Wind if I'm damaged and it's off cooldown."
(Note: It's a different thing altogether if a healer isn't DPSing because they don't feel confident they can pull it off without risking the other party members' lives. It's just the belligerent, "I don't care if I sit half-afk during dungeons; I'm a healer, that's the only thing I'll do," attitude from some people that I'm starting to get fed up with.)

you have to know for a fact that your tank will survive the next hit, otherwise they'll use Hello Ground and you know what happens from there.

Wait. I thought that was the DRG special skill that automatically Provokes the floor. ;)
