Recently I've wondering a few things (as a priest specifically)

How much aggro will a PW:S generate? Does overhealing of Renew/Rejuv count? How many points of healing does it take to overcome say, a Sunder when the tank has Defiance?

There are probably other things I'm not thinking of atm, but that's good for starters.

As I recall a normal heal causes 0.5 threat per point healed, overheals not being considered. (1:2 threat:heal)
HoTs don't even really have overheal anyways as they effectively stop ticking once the target is at full health. Its why druids/priests can manipulate any healing chart (even effective healing) so easily - throw enough HoTs out with 0% overheal and suddenly it looks like you are a god among healing classes.

HoTs still generate a small amount amount of overheal, nothing compared to a basic heal though. If your renew ticks for 400, and your target is missing 600 health, it's going to heal him for 800 total - the last tick that heals him to full still heals for the full amount, regardless of whether he's missing 200 health or 5. Granted, the overheal doesn't generate any threat, but it does have a very minimal effect on meters =p

PW:S generates 1/4th the aggro of the damage it would shield against. So if your PW:S protects against 1,000 damage by casting it you generate 250 aggro.

Incorrect.



Started at full health. If what you're saying is correct, the second tick should've healed for 391.

Hrmm you appear to be right. When did that get changed..... I could have sworn the second tick used to only heal for the amount required.

Yeah, I'm 99% sure that it used to be like that, and I'm not entirely sure when it was even changed :p It just works a little different now.

Does anybody seriously have a problem with healer aggro? It has never been an issue that I can remember. Even on Broodlord which used to be sensitive it was always a mage with their lack of an aggro dump who risked pulling aggro if the fight went on for too long.

The only fights which seem to be sensitive to healer aggro are more recent ones in aq that have mobs that do constant de-aggro of the tanks. Even then I've never worried much about Subtlety or other talents. The reality is when the mob de-aggro's the tank chances are very good they are going to come after a healer because we are the ones with the aoe aggro generation. So even if I could get 50% off my personal aggro generation, it just means they are going to go to the next healer on the list. Either case if a tank isn't there to pick it up or if I can't go bear in time, it means a dead healer. I dropped Subtlety from my talent tree ages ago and never saw much reason to pick it up again.

The only other aggro-sensitive moves are things like NS+HT on a pull. And I just put that down to healer stupidity. 10% off aggro generation isn't likely to save you there.

Hmm, there goes my little secret for lowering overheal %. When did Blizzard ninja change this? 0o

The only time when healing aggro is an issue (assuming I don't be a dumbass and ns+heal a guy 5 seconds into a fight) is on Post Emps trash atm, both Nullifier and Qiraji Champion packs. Sometimes it's an issue on Anubisath Defenders when they're not consistantly feared, but they should be.

It's not something that I think subtlety would help, though; most of it is from an aggro dump (ie nullify) ability from the enemy, and as a 8/11/32 druid those points are a lot better spent elsewhere.

tell the other healers on your side to stop slacking.
