The idea that we need to DPS must go.

Did you actually research how miniscule the heal gain from Det over DH hit is?
It's low enough that it doesn't even warrant melding Det over DH in the most difficult endgame content or first week. The difference between full DH and full Det meld is in the range of single digit %. If you die to an aoe in casual content that is designed to put as little pressure on healers as possible, it has absolutely nothing to do with melds. Nothing.
And there is a very practical reason to meld DH over Det: more healer dps. 4% more heal will never make the difference between having to heal twice vs just once. Det and DH are close than ever in terms of dps gain but DH is still slightly ahead and the additional heal from Det is pitiful.

All it means is that this person made a mistake and didn't use enough oGCD to heal the damage.
People make mistakes. If I would go to the forum and complain everytime someone made a mistake that cost me a little bit of time in a dungeon of all things, then I'd have to demand that dps only have a single button that does high single target damage with falloff so it's also their aoe button, tanks wouldn't have stances and only a 1-2 combo and nothing else so they can "focus on mitigation", any form of support from dps would automatically apply.
Someone made a mistake and you died.
So what?
This happened countless times to every single person here for various reasons: tank not having stance, tank not using mitigation, tank not using aoe, dps not using aoe, dps standing in the bad, dps standing in Narnia, dps with ress not ressing, co heal not healing, co heal not ressing ...
You had one bad experience. As far as arguments against healers melding DH or dpsing in general go, that's pitiful. And I have yet to see a good argument against either.

I refuse to believe that a stat that starts out at a third the value of other core stats actually brings significant value to anything.

Frankly, It's less about the numbers and more about the mentality which ends up making bad healers out of people. This wasn't an honest mistake. (You don't accidentally pentameld DH in a bunch of pieces of gear.) This was done with intent and it was apparent through the whole run of the dungeon. As the title of this thread suggests, the idea that healers need to DPS needs to go. Everything goes smoother when you have someone that's actually focused on helping maintain the people that actually bring the DPS.
