I have looked around the forums and haven't found anything pertaining to a +healing cap. If there's already something posted about this please let me know.
Anyway, I was talking to a friend this morning who told me that all the healers in his guild stop trying to get +healing gear after 1500 in favor of +MP5 gear because 1500 is the "cap" for +healing.
According to the rumor you gain 100% of your +healing bonus up to 1500 and only a small percentage on everything over 1500. Obviously shorter casts get less of your +healing bonus but he assured me that this was not the percentage loss he was talking about.
Assuming a 3sec cast (for me Healing Touch) he claims I would receive + 1500 to my base heal and only some unknown percentage for the additional 243 +healing I have above 1500.
I am going to sit down and test this as soon as the servers come back up but I figured I'd put it out there now. Has anyone else heard of this? Is there any testing done to support this claim? I'm extremely skeptical.
The only thing I can possibly think of is that he meant that while there is no programmatical cap to the amount of +healing you can have, there is a practical cap on it in that you'll see relatively little use in making your heals stronger after a certain point. And because of that the healers feel they're 'capped' at 1500 +healing.
This rumor's been around a long time and is quite false. Prior to the 2.0 changes it was trivial to disprove with Heal2, which for me healed for nearly triple it's base amount. The downranking change makes it harder to have a spell that actually is doubled in size, but it's still possible with HoTs.
Well, currently my rank 7 Healing Touch is about double the base heal amount, which is why I was skeptical about this rumor anyway. Thinking back I could have sworn that I was getting the full amount on my 3sec casts but I wasn't absolutely sure.
While I suppose it is now apparent that this is infact "wildly inaccurate" I have been considering what Chicken said earlier. I wonder how much my current +healing lends to overheal "in practice". While I'm generally no where near the top of the overheal meter a 3sec cast (Healing Touch) does get beat out, often by Paladins and their FoL spam.
Perhaps I'll put in more Intel gear for a larger mana pool and a small amount to +healing thru talents.
There never has been a cap to +heal as far as I know, and I used Heal R2 exclusively for a large portion of Naxx due to its retarded efficiency and it was healing for easily 5x? 6x its base amount iirc.
Regarding a "cap" that players put on themselves - I've always gone conservatively for +heal - I've never been a huge fan of exclusively stacking it, and always favor regen in place of +heal. I like to settle at round numbers as well - so I'll probably continue to gear until my FOL's are 1500 (w/o BOL) and my Holy Lights are 4k (w/o BOL) consistently, then just stick with regen/crit/stam. This also makes it alot easier on me in terms of theorycraft since I am bad at math, and adding 4000 up a few times is easier than adding 4122.
That being said - with alot of the current encounters I find myself using my Gladiator's set more and more. It could be because I tend to be that overzealous retard Paladin on a raid that taunts at the first sign of a mob not being on a tank, but gosh darn it I work hard to maintain that role, plus all the damage I take results in more mana for me! (Not many other healers have picked up on the fact that I take cleaves a little too often to chalk it up to "oops".)
But really your mileage will vary - as a Druid and being so HOT centric I'd imagine you want alot alot of +heal compared to a Paladin. But what do I know, I stand in cleave.
EDIT: New Post above me.
One thing I think alot of healers that are spirit based do not think about is potential regen during a fight. With the amount of Spirit some of you guys are reaching now a days - aren't you overfilling on Innervates? Wouldn't stacking a little more int help out in terms of giving you a "bigger bucket" to fill when you do receive an Innervate? (assuming you do). My memory is hazy, but I think I remember in Naxx getting an Innervate with 475 spirit and being almost FM going from less than 1k to 8k on my Priest. Does this situation happen to you?
Just to clarify... I'm specced 27/0/34, so I'm not HoT-centric and I'm not stacking spirit.
I use Healing Touch as my main heal and throw off HoTs on DPSers who take infrequent damage just to get them back up to full.
That being said, yes, I'm thinking about more Int as a means of having a larger pool but I generally don't "overfill" with innervate. The reason being is that I know exactly how much my innervate will regen and use it accordingly. Additionally, I use Drums of Restoration and potions very early and can generally last through most fights without ever having an innervate on me.
I guess in a matter of speaking healers do feel "capped" at a certain point and the only reason up to now that I've never really questioned stacking +healing is because I like using Nature's Swiftness + Rank 13 Healing Touch to save tanks; I can crit mine for well over 9k which is often a wipe-saver.
Because my own mana usage has never really been a huge issue I guess I've never considered stacking MP5, though in the long run it seems to be more and more appealing. As the fights get longer and the mobs hit harder I wonder where the real "cap" for both +MP5 and +healing is. Having to use higher ranks of heals to compensate for harder-hitting mobs obviously takes more mana, making MP5 more useful. Converesely, having more +healing will allow you to stay at whatever rank you like to use and maintain your mana that way.
Well the bulk of healing is done with Paladins (usually 2-3) and 2 Holy Priests, with 1 or 2 Resto Shamans covering everything else (cleave happy melee fall into the equation here) with Chain heals. The tree fits in perfectly since he can hit people not topped off, anticipating damage, or Warlocks crying about mana or about the fact that they didn't get a Shadowpriest. Tree is usually one of our top effective healing done as well with incredible efficiency - whereas us single-target stuck-in-the-dark-age spammers are bottoming out at 40~% sometimes overheal. (I like to think alot of that is chalked up to crit. At least it lets me sleep better at night.)
