What I meant was that whenever tank healing actually gets difficult (which for 80s is on hard hitting bosses in raids) you'll get your Penance on cooldown (and PW:S and Renew are already up) and have to spam Flash Heal to keep the tank up. Without Penance, your rotation in these situations would go from "PW:S>Renew>Penance>FH>FH>FH>Penance" to "PW:S>Renew>FH>FH>FH>FH>FH>FH>FH>FH ad nauseam" which, to me, having been 80 for so long, would feel pretty weird.
Yeah, I haven't healed with a priest in a raid setting since, I think, summer 2007? I haven't raided at all in nearly two years.
I remember shield being much less important back then and of course Penance didn't even exist. I don't think Flash Heal was all that good back then, either.
As a tank or as a healer? In the case of the latter, he has to lower his standards for when to use them. I was in that situation once when we got a priest in my guild who used Guardian Spirit on anybody who went below 20% rather than saving it for 'that time the tank got low' which never occurred. Seeing him do that made me figure that the smart move if you're never using your cooldowns (as a priest) is to simply use them earlier to make your life a lot easier.
As a tank. The problem is that there isn't much use for tank CD's if you're constantly sitting above 90% health, like, ever. As a healer, I use the few CD's I have so far enough, I'd say (although I lost Desperate Prayer with respeccing and abuse Inner Focus to get Holy Fire crits, mostly), which should leave him with even less reason to ever use any of his. I am looking forward to our first few heroics in comparably crappy gear.
They changed that, though, didn't they? Iirc it's 20% healing and damage now, which is really meh. Worth it for AOE grinding or something though, I suppose.
Yeah, there just isn't much else I can glyph, really, before I can get Penance. It's just that glyphing PW:S seems kind of pointless, at least until instances start getting hard enough to bother getting any healing glyphs.
Also, I am leveling nearly purely in instances now. I did one quest today, and that was the robot chicken one.
