Lies, damned lies, and statistics!
Gevlon, the Greedy Goblin, certainly knows how to push a point, often directly at odds with many an old, wizened head (I kid, I kid, I'm sure they both have a couple of decades left in them!). But he's essentially right, in a very limited way.
I'm not going to say that healing meters are "teh bomb". Not at all. But they are as useful as DPS meters. DPS meters are not reliable. DPS meters are lying clumps of rotten code that can't report the same DPS between two runs, much less two players. I don't know how many times I've seen our e-peen obsessed enhancement shammi crow about topping our GM's mage, only to have three people post that he didn't, and show different values between them, to boot (Programs like Recount suffer from the same thing across the board - events beyond a certain distance are not noted, and excessive traffic in the data channel will cause events to be dropped arbitrarilly. Only an idiot trusts these things once learning how they work).
So I don't 'get' the noise about healing meters. Any experienced DPSer - or raider, for that matter - knows the value of DPS or healing meters, and that's that. Any protestations to the contrary are, in my mind, simply being disingenuous. Especially long time bloggers, who should know better, and who weaken their arguments by pretending otherwise.
All this is simply to put it in perspective. Gevlon is no more out of line saying that one should maximize HPS than BRK is in saying that you should maximize DPS. HPS and DPS are not the whole story, and any experienced player knows this.
As an example, how does one account for a hunter's CC duties in the Moroes fight pre-nerf? Well, if Moroes didn't kill the healers, somebody was doing his or her job, that's how.
How do you really measure that? You don't. Your raid leader has to have his or her eyes open, and know what is going on. A raid leader that doesn't know that a particular hunter is dropping the ball on CC, or that a particular healer is right on top of things despite the numbers - is a terrible raid leader. That's all there is to it.
So the whole argument is a paper tiger - a thing that looks like a big deal, but has zero substance. At the end of the day, any competent raid leader will be using meter numbers merely as starting points in any meaningful evaluation. Really, sometimes it's like people are just making noise to make noise.
Well, no such thing as bad traffic, eh?
