healer with peace and harmony could it work?

Probably something wrong with my math, but the consensus is that Peace and Harmony is an awful energy management elite compared to what else is available. Nothing is wrong with your math, but you need to look at it in context to see what it means.

Peace and Harmony at 12, as you said, gives 78 seconds of +1 energy regen, restoring 26 energy over its lifespan. Subtract the cost of the skill, 5 energy, and it nets you 21 energy over 78 seconds, or an average gain of 16 energy every minute. It also has a host of drawbacks for you to build around.

16 energy per minute from your elite slot is *pathetic*

Let's start by comparing the skill with Glyph of Lesser Energy, which doesn't have any attribute point requirements. It costs you 5 energy, and saves you 15 for a net savings of 10 per use. It's ready for use every 31 seconds (1 second cast, 30 second recharge). If you use it as often as it comes up, it'll net you roughly 19 energy per minute. Even if you slack off on it a bit for better timing, as long as you use it every 37 seconds (giving you a 6 second window) you'll be outperforming Peace and Harmony in terms of energy management.

A low spec (7) Offering of Blood will cost 5 energy per cast and net you 14, on a recycle of 15.25 seconds. That averages out to over 35 energy per minute, more than twice the output of Peace and Harmony, and that's with minimal attribute investment. Maxed, Offering of Blood nets you 63 energy per minute, roughly four times what Peace and Harmony will give you.


Or just look at more efficient elites. Heal Other is your money heal on that bar - why not replace it with Word of Healing? Even if you only use it three times per minute instead of Heal Other, you've already saved 15 energy on healing, equaling the output of Peace and Harmony with one less skill slot and a let less restrictions. Realistically, you're going to be using Word of Healing an awful lot more than three times per minute. In a crunch, you'll be using Word of Healing every time it comes up, which at a 4.75 second recycle will save you...63 energy.

The potential use of Peace and Harmony would be the ability to maintain it on all of your Monks, but the recharge kills it. That leaves Peace and Harmony as it is, as a learning tool. The skill is terrible, the worst energy elite in the game. Once you understand why, you can safely abandon the skill and get better at the game because of it.

Yeah, let's dedicate an entire character to running a bad skill. Great idea. Have I said that? I said dedicated enchant master, not dedicated P&H user.
That means enchants like Healing Seed, Healing Breeze being boosted from 10 secs to 16.

Now do the same with P&H with 16 divine favor (staff 20% enchant+Blessed Aura 37%): 94*1.57=147.58 , 148/45=3.28...
Now if you want to support more that 3 monks with P&H, get ranger secondary.

I think what Bast was trying to say is regardless of how many characters, or "enchant masters" you dedicate to keeping peace and harmony on a couple of monks it still doesn't change the solid fact that the skill is a steaming pile of shit, and that creating a character around it is a very, very poor idea. I also thought I agreed that this skill need a boost, so don't think that I try to show you all how P&H is great

peace and harmony once was decent when you could keep it on 2 monks who could then work keep all their att points in monking but now too many things end it
my suggestion to help it out:
double the energy regen, rework the nature of it so spells like aegis/divine boon/glyphs dont end it and lower the duration about 15 seconds Doing a few of those things would e nice. Less restriction, keep the 1 pip but make 15 sec so it can be kept up. But all of themare overkill

If it was a stance rather than an enchantment, and/or it gave double the energy, and/or its recharge was faster and/or it wasnt an elite skill, then it might be worth running. As it is there are far better non-elite skills for energy management than this without even compaing it to energy elites. If it were both a non-elite and a stance, then it would be worth running, maybe. I don't know if I would waste a slot for it even then.

what about this?

Peace and Harmony {Elite} - Stance
For 5...25 seconds, you gain +1...2 Energy regeneration. Peace and Harmony ends if you attack or cast a spell that targets an enemy.
Recharge time: 30 seconds
Energy cost: 5 energy

Um, yea... at 16 divine favor it would give +3 energy regen and will last 30 seconds.
It would rule this way... and would only be usable by divine favor monks...

And no, it wouldn't ruin any other energy management skills. And all the small arena Mo/Me would cheer! LOL....

The fact it would be a stance removes the ability to cast on another (Monk) and as long as the stance breaks if you attack would fit perfectly. It would likely be too good for a high Divine Favor Boon monk, though. If Anet did anything like that I am sure the duration would be 10...LOL.

Making it a stance also limits the use of other stances and allows it to be countered by things such as Wild Blow.
