Just because they have mongoose on the weapon they log off on or use most of the time does not mean they don't switch to a weapon with Blood Draining for certain fights. That's kinda what they do. To find out who actually does what, you'd have to ask them somehow (in-game or forums, etc).

Sorry, to bring something back up that lies so way back (somewhere on the middle of page 23), but I've been wondering ever since and since I plan to restart playing soon and I couldn't even find this mentioned anywhere, nor less any detailed explanation. I'm wondering basically the same thing as Negoveio here:

Why isn't anybody really considering Effulgent as a meta? Is it really that bad? Are there that few abilities that count as doing spell damage? Could anybody please enlighten me? I'd be sooo very greatful!

The armor meta is only something like 600 armor so on a few fights effulgent might be better. The fights I've considered it to make any real difference are sartharion 3d, anub'arak heroic and lich king heroic.
If the majority of the damage you take is spell damage, or if spell damage is the only thing that really threatens to kill you then you can go for effulgent.

Would love to hear some of the top guild bears explain their Blood Draining. It may be EH, but everything I can find, all the testing I've done, etc, all point to it being utterly terrible. It's got a 10sec ICD (last I checked) to generate a single charge, so when it procs, it'll heal you for... what? Probably 1k? Can anyone point to any logs where it shows it being beneficial?

Also wanted to explain the bear trinket calculations in Rawr, since I see it asked a lot. In this most recent version, I modeled several trinkets that weren't modeled, and significantly improved the modeling of a few that were only barely modeled. Everything of any significance should be fully accurately modeled now, with just a couple exceptions, noted below. The results may not be what you expect though.

Unidentifiable Organ: Very very strong, assuming you can keep the buff up. It's very situational in that regard. Fights where it sucks would be... Saurfang, Putricide P3, Valithria. And a few fight's it's mediocre where there's just a single slow hitting boss, making it likely to fall off frequently; Sindragosa, Blood Queen.
Black Heart: This is an ilvl200 trinket from ToC, yet it shows up really high in Rawr... why? Well, short answer is: It's really good. Decently high proc chance, and a ton of armor, along with a decent chunk of stam. However, there are 2 issues here. First, it's doing calculations to find your expected uptime of it, and from that finding the average amount of armor it will give you. That's a problem because it doesn't yet take into account the fact that you could be over the armor cap with that proc (but that's only a problem is you're really decked out, nearly full 277s). Secondly, it counts that averaged amount of armor like any other armor, which contributes to survival rating. That goes against the standard meaning of survival rating as being guaranteed reliable survivability. So you probably should consider its proc as having only partial survival, if at all. Still, it's a very very strong trinket, and until you have some of the other really top trinkets, it's probably worth using.
Satrina's Impeding Scarab: Solid all around, scales fully with the ICC buff.
Corroded Skeleton Key: The Use for this one isn't modeled. Last I checked, its Use didn't benefit from the ICC buff, but I haven't tested that lately; if anyone knows different, please let me know.
Glyph of Indomitability: Passive armor, very strong. Its Use is kind of weak, but worth using on a few fights, when you don't have the top trinkets.
Sindragosa's Flawless Fang: Crapload of stam. 'Nuff said.
Corpse Tongue Coin: This one is tough. Very situational, but a strong contender in a few situations. Its passive bonus being dodge rating makes it rather weak in all ways but raw damage reduction, which usually isn't a high priority. However, its proc is on a very short cooldown (30sec) and gives a huge burst of armor, when you really need it. For example, it's wonderful for Soul Reapers. Modeling this is very difficult and subject, so in Rawr it's modeled as just a 17.5% chance to proc on damage taken. That probably makes it think it procs too often, but compensates for the fact that it's averaging out, so doesn't give any value to the 'smartness' of the proc, since it procs when you really need it.

I usually don't pay attention to these threads here (for obvious reasons if you've been around here for very long. These threads aren't what they used to be, to say the least), but I'll try to keep an eye on this one for at least a few days. And as always, if anyone sees any mechanics or playstyles or whatever that Rawr doesn't cover, contact me directly; I want to know about it.

Ok then Astrylian, since you're gonna be watching the thread anyways I have a question for you. Do you think the corpse tongue coin is a viable alternative to one of the stam trinkets for Lich King (Normal Only)? The way you worded the explanation for the trinket made me think about how much health I had when I first started tanking 10m normal ICC. When we got to the lich king, Soul Reaper would bring me to right about 35% health, and that armor would be very very helpful if healers were pre-occupied with something. Mind you, I understand it's still very situational, and I am still a firm believer that a more consistent EH trinket would be better. However, do you think it's viable enough to be not totally useless?

Although im not "top" Bear by any means, im still working on LK Heroic as such. My reasoning for Blood Draining is in its capability(however small and irrelevant it might be) to help surviving worst case scenarios (soul reaper). Its correct that it wont stack to 5 between soulreapers, but what good is mongoose? Its less reliable and based on avoidance where blood draining *will* heal for a small amount. The way i see it(since modelling these things are exceptionally tricky) all I can hope for is to minimize RNG. That said, I never thought of using the Corpse Tongue coin, since that would contribute a significant amount of EH when it procs after a Soul Reaper. I've been wanting to experiment with Sindras Fang on-use as a means to resist the second portion of Soulreaper, as it is shadowdamage, but were not reliably gettin to Phase 2 yet. Anyone tried this and recorded resist amounts?

I do like Rawr as a means to comparing gear, but with regards to trinkets I just dont see how averaging out procs and on-use functions gives any sort of meaningful data, when we really need to put it up against incoming damage profiles which are quite different from boss to boss(This is'nt meant as a bash to Rawr, btw) Trinkets are just inherently different from other gear slots in that respect, which is where discussing them from a boss-to-boss basis is more relevant.

The second part of Soul Reaper cannot be resisted. The damage is only modified by global reductions (like Barkskin) and absorptions.

Also note that Blood Draining does not guarantee a heal when you're under 35%; it only does so if you haven't been brought under 35% in the last 10 seconds and have had a proc. That's the normal case, but it is not necessarily the case that it will always occur.

You can use it to resist the first hit (the application) of Soul Reaper, but not the damage you take at the expiration of the debuff.

Over the course of 21 attempts on LK heroic Blood Draining proc'd 34 times normally, and critically healed 3 times for a total of 83264 healing.

83264/37 is about 2250 healing per proc. I don't understand where people are getting 1000 from.

I don't think the blood draining vs mongoose is a clear debate. I used blood draining for most of my guild's learning attempts on LK Heroic, and I could not find a single instance where it was a big enough heal to make it life saving (eg it plus a heal from a healer saved me, where the heal from a healer alone would not have done so).

I found the buff from Mongoose to have 26% uptime in our Heroic LK kill, which considering that our strat involves me not tanking on the ledge transitions, as well as the time lost in Frostmourne room, is pretty good uptime.

I'm not going to say any bear using Blood draining is making the wrong choice, I think it comes down to personal preference as either will work.

I need some help as one of two HLK 10 tanks, in phase 3 if my challenging roar is down and I have to soak spirits I cannot seem to grab them on to me. By the time the spirits get to the spot on the inner edge of the circle pattern where we soak they are still somewhat above my head and I can get them if I have challenging roar up but if it's down I have tried swipe, and demo roar but the abilities either don't work or the spirits are too high up for those to effect them, even with me jumping to try and get extra reach. Is there something I am missing? Are there any tips anyone could give me? Any help would be very appreciated.
