I don't think anyone is saying that PWS is a bad raid heal, but instead that if you're raid healing as Discipline consists almost entirely of PWS spam, you could probably do more to help your raid. If you're raid healing as Discipline, your healing should consist of a combination of PWS, PoM, PoH, BH, and maybe the occasional FH. Take Blood-Queen as an example. PWS is definitely useful for the fight, like on the Pact targets, saving people that get splashed, etc. However, if you're mindlessly spamming PWS, then you're actually hurting raid HPS. Sure, your PWS will virtually always get the full effect, but if the target is at or near full health, then a Holy Priest or Druid HoT on the target will tick for overheal while your PWS absorbs the incoming damage. That may not seem like a lot, but mindlessly doing it can ultimately waste a significant number of HoTS over the duration of the fight and those GCDs could potentially have been used on other spells or at least on other targets. At the same time, as harky pointed out, you can actually get superior HPS with a PoH, even if you have a considerable amount of overheal, so you can help top off a group and then continue to let the various HoTs work to keep them topped off.
Either way, this holy PoH vs. PWS thing is basically a red herring anyway. The real point is, if you don't need the mana, which most Discipline Priests don't on most encounters, and you cast PoH at all, the PoH glyph is useful. Hell, chances are there are at least a few opportunities where even the most PWS-spam friendly Discipline Priest ought to consider casting PoH instead of PWS. And in either case, in a fight where you're raid healing, whether it be PWS spamming or mixing in PoH and BH, FH will make up very little of you're healing because it's flatly inferior to either option as a raid healing tool, so why bother having the glyph for it in those situations?
So really, the simple answer is, if you're having mana problems AND Flash Heal makes up a decent amount of your healing on that fight, the Flash Heal glyph is worth while. If you're not having mana problems, even if you're casting Flash Heal a lot and barely using PoH, there's no reason to take a glyph to improve your mana situation if it's already fine. Similarly, if you are having mana problems but barely casting Flash Heal, what good will that glyph do you?
