Nymphae 80 Night Elf Holy Priest (Stonemaul)

Due to the excessive and costless spamming, tanks and dps classes shouldn’t die at all. In fact because of all this spamming priests heal better as a ghost than when they were alive. Without the glyph, its 10 seconds flat. Spam all heals in 10 seconds. If the boss doesn’t die by then the fight is over. But with the glyph healers have a good chance to convert this 10 seconds into 20+ or even half a minute if they spam their flash heals fast enough, giving the group enough time to finish a boss fight.

In arena/organized pvp, correct me if im wrong but people usually target the healers first. So when they die they become god and spam flash heal on whoever is remaining and keep them alive without worrying about pushbacks, or dying (they are already dead). And if they have the glyph, they have a good chance to keep spamming heals throughout the entire match.

In my own experience the other day, somewhere in Borean Tundra, i was alt-tabbed away from the game. By the time i came back i saw myself in spirit of redemption form with around 5 seconds left. In front of me was 2 lvl80s from the opposite faction and a lvl71 from my faction. Obviously they killed me while I was afk and I saw them attacking the lvl71 guy. I started to spam heals on him and kept the little fellow alive for more than half a minute before i managed to die. Although the lvl71 couldnt do much due to the huge lvl difference, but if he was lvl80 he could have killed at least 1 of them during this time.

Although It’s true during raiding bosses that lasts for several minutes, this extra 15-20 seconds isnt as useful, but still the uses it has for normal instance bosses, as well as healing during pvp would place it in what you call as “Questionable Glyphs” section rather than near useless.
