Well I've used the glyph since it was 5 yards, and while the 20 yards is nice, I think 8 yards is too small. There are a few fights that the melee DPS has to stand more then 10 yards from the tank, and as a tank spammer the glyph becomes useless if people are doing what they should. If this glyph stayed at 11-15 yards I'd be happy with it, if others think a 20 yard non-smart heal that procs off of the biggest, slowest, and most mana intensive spell we have it OP, then lets make a compromise that works, not a nerf into uselessness.

As it has been pointed out, this is not a smart heal and it does tend to just overheal, and even if it isn't its only 1.5k-1.8k(on a holy light crit, not critting the second heal) and even to get that you have to be spamming holy light to get any real healing out of it. You also have to think of it as a 1k(from a well geared pally HL non crit) is really not that much. Being decently geared I can spam flash of light and shock of light when needed almost endlessly without worry, but start just tossing out holy light and you go oom fairly quickly.

Not playing a priest or looking onto their recent nerfs, I'm under the impression they now have a 6sec CD just like holy shock, the 3rd healing spell I have and only instant cast. It's a different play style, I get no dmg mitigating sheilds(well the one but its kinda odd and doesn't work in the same way) so I have to be prehealing if there is going to be any big spike dmg, and it can be very close sometimes to get the holy light into the flash of light spam without the tank going down, more so if the dmg was unexpected.

Learn your class, play your class, and until you see pallies in blues and greens topping you on the effective healing charts all the time, it might not be that we are OP, just that we know how to play.

Everyone needs to remember that this glyph came in during a priest nerf. From what I've read and heard a lot of priests had lots of their healing from the nerfed spell, and while they are getting use to new rotations with the CD they will heal less, but once they get back into it they should be fine. Just cause you're on a learning curve doesn't mean we shouldn't get any usable raid heal.
