As a beginner healer I think the leveling dungeon difficulty is actually perfect and I think any more difficulty in dungeons might turn off people who aren't particularly confident in the role.
This may just be a self call out of how bad a healer I am but I think this game should not just be for those who are experienced and I am aware im not some giga healer but in the same vein I have played every class , and i have done a few savages while current so I have the game basics down.
I have just finished levelling Astro through Shb and EW leveling dungeons and I let the tank drop a fair bit due to being a bit new and trying to balance the card and dps buttons with the heals.The Idea of tanks being nigh unkillable only really applies to 'good' tanks. over the past 2 weeks I've even had warriors with blood-whetting go from 100%-0% in the space of a couple of malifics while I scream at my screen for them to just press any button due to just not using any of their buttons on w2w's ( or a few where ive blown all CD's trying to keep them up and ive had to resort to benefic spam and then getting yelled at for not healing enough). with the difficulty of dungeons being firmly in the realm of casual content i think a good tank should be able to do it without a healer , just like a good healer should be able to keep a party up without a tank and there isnt really a problem there.

I haven't healed a savage but my wife was our healer and it looked pretty stressful( way more than warrior anyways) and as far as im aware the drama that kicked this off was Xeems cleared a leveling dungeon with no healer .

Im really not sure what the drama is about .
is it specifically about talented healers not being engaged enough in levelling dungeons ?
not enough dps options ?
community opinion of healers ?
