Well having to heal different tanks is me failing at healing correctly, but I do see the flip side, that the tank mechanics are forcing the tanks to deal with the fact that their class mechanics are causing the healers to have to play differently.
I also accept the rest of this too, the dps playing badly not saying close is our weakness, but we are stronger than most if the tank is playing badly not using CDs correctly.
I'm not talking about not stacking when they should be, that is a fairly simple concept. I'm talking about fights where you need to reposition frequently and with a slight spread mechanic where they could be with in 12.5 yds, but with that much moving around they just are good enough to keep the minimum range apart while staying with in the jump range of CH. Or grouping in such a way that they are far enough apart but many could still be in HR. Rhyolith was one of my examples, sure they could have stayed closer on the last phase, but staying close to each other and in the HR while avoiding the lasers and doing dps was proving to hard for them, while the I struggled with RT > GHW > GHW our druid was able to continue to heal the raid.
But as Keiyra pointed out, our druid wasn't exactly able to drop 120k crit heals on the tank, so there you go.
And a lot of the other people were pretty much saying I could do it why can't you? Which is close to what your argument was boiling down to.
So I still say no just because the others are playing badly isn't a reason that I should be harder pressed to heal than other healers. However, I do rescind my rant as it has been pointed out we are better than other healers in managing other situations of others playing badly.

Moving on to discussing MOP
What I'd like to see is if a CH cast can out perform a glyphed RT.
If that's not the case it seems like RT glyph would need to be nerfed or why ever cast a CH.
And that would be a comparison of CH with and without a RT target.
I'd think if glyphed RT performed less than CH then that would solve us using it for stacked fights. Even if CH is just better when cast off of a RT target.
I think it would be kind of interesting to use both glyphed RT and CH for spread out healing, but if a glyphed RT out performs CH even buffed by RT target then using the CH glyph probably would be inefficient use of a glyph.
