Thanks for posting Nuttann!
Btw, I'm probably going to cut/quote up your post here. It's nothing personal either, we're just discussing more effective ways of healing. So that's my disclaimer, and I'm sticking to it! <em runs>
To be fair, I usually have max AAs a couple months into expansion. This may make a difference as my heals do a fair amount on their own and crit as frequently as they can. I have used the blessing method above and found it being less effective for me in many cases.
If the tank lives and heals always hit for full amount, then the math definitely works out to blessing being huge. There would be no reason not to use it unless some critical cure or debuff would have to go. Yes, I understand the math.
However, there are two factors depending on the situation that do lower that.
If normal heals are maxing out the tank or the tank is returning to 100% based on all the heals hitting him, then a twin heal doesn't heal anymore than the normal.
You appear to be describing a singular tank situation; whereas I assume you mean plural. Because it's not just about a single tank. Utilizing a twin at an opportune moment; doubling your next two heals has a huge impact depending where
you choose to direct them. That's the key thing here, it's not about whether your heal has landed on that single tank, but what you do immediately after with the twin power at your disposal. You may quickly look at ETW and find two other tanks in trouble, and decide to drop a heal on each before going back to your initial focus. Now, given your twin was up, your heals just had a potentially big impact on their survival, perhaps even enough time for someone else to cover them or finish casting their heal.
Following the above example though, maybe everything is fine in ETW, but your current tank focus is getting ripped a new one, and getting a twin in there may pose too great a risk. Obviously it's a judgement call. I'm not saying twin or bust, but I'm saying a high priority should be given to making it in your casts if possible, unless you feel at the moment the risk of losing your tank is too great. A judgement call, like we all make as healers. Players die based on our calls.
I admit, I'm a very aggressive healer. My mindset is, keep the twin up, always, period. If I'm losing ground on a tank, between blowing every safety I have, I'll still maintain priority on getting the next twin up to regain ground on the tank that's having trouble. Because RNG is not our friend (it's definately not mine, if you've ever seen me /random), we shouldn't be relying on it to save someone elses life in the virtual sense. Twin removes the RNG factor; supplanting it with the power of heals that we know will crit, guaranteed. Demi-god status is what it does.. Like after you eat pie.. Mm.mm, Hrmph, wha? Oh yeah sorry. moving on..
The other factor is time between heals. I find this is important to me. The one sec cast of blessing plus recast is sometimes huge. Yeah, I can follow up with invigoration, but that just turned my 0.5 sec heal that I try and keep up for real emergencies into a 1.8 sec heal.
With the above in mind and twin up, your 0.5 sec heal will always crit if/when you choose to use it. This is what I'm trying to get across here. It's not about 0.5 sec turning into 1.8 sec. But the fact is, if you're using your fast 0.5, I suspect your target is in deep shit, and having the heal do double is all that more important then doing half the heal and then having a fart in the wind chance of possibly gaining ground with what after that? A slow 2 second heal? Sure we're talking hypotheticals here, but just saying. Think about it. Double heal, 1.8 sec, or that normal heal, pray it crits at 0.5 sec. I'll take the double heal, any day, and I'd wager the tank would appreciate it as well.
The moment you start losing ground, you've already lost with conventional heal methods (ie, a patch and banking on RNG). You need the twin there, always, so whether the tank needs that double heal or not, when the shit hits the fan, it's there, guaranteed.
Pardon my langauge btw, but it's late, and please don't construe the above as being sarcastic.
Maybe it was just a different healing team, but I have found that I lost more tanks with the gap in healing to get the 2x twin cast proc than keeping heals going even though not doubled. This time between heals is crucial thing for me and why I use blessing less that others. Especially times when I am constantly switching targets.
I've saved more tanks with twin healing than lost. But of course, we're going to lose tanks simply due to some situations not even we can pull a heal out of our ass in an epic scene of Halfling pie eating glory. Ass, pie and glory all in one sentence. I'll wait for Huevos to come in here with a funny retort.
I agree that the time between heals is crucial, but it's the judgement that matters. Obviously misjudging a twin can potentially result in not landing a subsequent heal in time. Whoopi do, the fact is, it takes practice to learn to make good judgement calls, and as healers, we both know this. This type of healing goes against conventional form, but it's necessary to keep pace with the game by adopting and adapting to our environment; both group and raid. I've been using twin for a long time now. Coupled with the nuke/heal and heal/nuke lines; it's by far the most powerful method for healing in game.
Yes, those twin casts give more chances to crit a heal which show up in the spam, but looking at my logs has shown a lot of them doing 0 actual heal or less than a full single heal total to target for me. And many of those time, ducking was not an options since the tanks health showed damage until after the heal, but someone else's hit first.
Lots of your heals are going to land for zero. I wouldn't stress over it. What's important is, when it matters, the crit is there and there's no requirement to pray to your god to make it happen.
Are there times when it has benefitted me, yes. But, not as much as it has for others apparently.
I'm glad it has benefited you at times, I hope in the future it does more frequently.
