Once I got my second piece, I noticed a massive increase in regen and longevity; it was to the point where I was almost never using super mana pots. I'm a firm believer that if you're not chugging them, you could increase your stats elsewhere. Its to the point where I've been dropping mp5 in gobs for more +healing and stamina.

Just wondering if anyone has done any theorycrafting into how much mp5 the set bonus can equate to.

For numbers sake, I went from 402/172 mp5 to 409/148 mp5 (some of the gear I changed had more spirit. That's why the non-casting number went up). It still seems as if I could drop more while casting mp5.

Thoughts and feedback on this set-bonus would be appreciated.

That's a moot point. If you are chain casting GH and overhealing on each and every single cast, something is wrong.

I think this is a very decent set bonus though. It gets a lot of criticism because it rewards poor play, but I think overheal occurs naturally and is inevitable. Unfortunately, I don't have this bonus, but looking forward to getting it.

That would depend largely on the encounter, and the healing tactics of your fellow healers. As you mentioned yourself, overhealing is inevitable. And chain casting GHeal certainly isn't always a poor tactic. It is a good (and necessary) complement to reactionary healing, because it provides far greater sustained raw HPS compared to any other form of single target healing.

That would depend on your definition of poor play. In my book, poor play is pure reactionary healing. This set bonus emphasizes just the opposite: chain casting GHeal, even if at the start of your 2.5 second cast the tank is full health.

A few tangential questions.

The priest set bonuses seem backwards to me. I would much rather have priest tier 4 4/5 bonus than tier 5 2/5 bonus, although I do not have 2 pieces of tier 5 yet.

I am curious as to whether healing priests in Hyjal and BT switch between tier 4 and tier 5 depending on the encounter.

If one was to get tier 5 or 6, which gem would you lean towards for the yellow sockets?

I can't contribute a lot of mathcrafting, but I got my 2nd piece yesterday and its fuckin awesome

It is the best setbonus ever designed \o/

T4 4/5 sort of implies you're casting mostly Flash Heals and a few Greater Heals for spike recovery. While this might make sense pre-1.10, when Flash Heal was the staple raid heal, it really doesn't make sense now.

Edit: Nvm. Too much time playing my mage.

The global cooldown doesn't effect the casting rate of GHeal at all. The GCD is long over by the time you finish casting a 2.5s spell.

Latency would indeed alter the results, but I really think the base assumption that every cast overheals introduces way more error to an estimation of its value than lag does.

125mp5 = 25 mana/sec = 100 mana/4 sec.

Umm...that's just...bizarrely wrong. The GCD starts when you START casting. Since a talented GHeal is 2.5s, the GCD ends well before the spell does, so assuming zero latency, you can cast 1 GHeal in 2.5s (hence 200mp5). If we assume, oh, 200ms of lag then it might take 2.7s or so (or maybe 185 mp5). But it'll never take 4s; the GCD doesn't work that way.

Yes, this is correct. I am a moron.

I remember when I figured out that the T4 2/5 bonus broke on damage. "Wait... it's even more worthless than it looks? That's impressive!"
