I have question if it is worth to swap 2h tanking weapon to dual wield fast tanking weapons in situations when there is nothing else to do. I mean now we can postpone runic strikes as much as we want cause we can use them any time as well as usual HS/DS strikes.

Swaping to dual wield can drastically boost our runic power generation via Scent Of Blood. While 2h 3.5 sec strikes require 10.5 secs for fully eat SoB buff, two 1.6 secs weapon easily eat SoB in 4 secs.

I had the same exact problem with Blood Parasites in 4+ instances. They did not proc often and the times they did proc, the healing did not seem smart. Our healer was DC'ing as we ran through CotS and one of my DPS noticed my worm healed him (over 80% health at the time) while I was running around with 50-60%. I checked recount and sure enough my worms were blowing up and healing DPS rather than me when I had pretty much all the threat and less health (as percent).

As far as reforging, I like mastery a lot but the two things I am still questioning is Rune Strike and Diseases.

Rune Strike - if it is as it was last night, you may benefit more by gaining threat from dodging and parrying attacks allowing RS. If that's the case then it'd probably be better to reforge to dodge/parry.

Diseases - at times last night I found myself not refreshing diseases because on single target, it doesn't seem to be an issue. Why give up a DS to put diseases back on and miss that heal and shield? If we do in fact go disease-less than I am sure Mastery would likely pay out.

IMO, Blizzard will likely change RS so it is more ideal than now (i like the 30 or 40 RP cost on the GCD and not proc-ing off dodge/parry) and they will make sure it's crucial to keep diseases up.

If that's the case it'll likely be a scenario of if you have dodge greater than X% and parry greater than Y%, reforge excess to mastery (based on DR limits).

Does anyone have DR or conversion for dodge and parry now?

EDIT: Love the changes though! Feels good, I just have to remember I have bone shield now!

I was discussing the organ trinket with a pally tank last night and it's now almost better to use the beerfest trinket since you get the constant stamina with it. With the loss of the armor bonus I don't see the organ as useful now.

As for the bloodworms, I only ran one 5man last night but noticed my blood worms seemed active almost every pull though. I may have just been lucky.

One thing I noticed though is that the grip auto reset didn't work on any immune mob. I got threat, but no grip to me and no reset of the skill. Anyone else see this?

I only run one heroic dungeon last night. I have huge amounts of time where I had nothing available (though reading through the above posts this could possibly be because my old macros were in tact with runestrike linked to everything).

We blasted through the instance in record time, while I didnt see a large increase in dps numbers everything died much faster. Pestilance now has no graphic (bug?) and bloodboil just about hit everything in a 2 mile radius. (ok not 2 miles but it was huge).

Anyone work Festering Strike into a rotation? I was hoping to test out threat a little better but everything was dead , including bosses in a few seconds so was hard to tell. Any one notice threat issues ?

I had quite a large increase in hps about 4k more than prior to the patch unbuffed

Will be interesting to see what now can be traded for Mastery. Did anyone actually manage to run anything noteworthy to get some better data?

I had this kind of luck as well. There was incredible up-time in the 5 mans I managed to run last night. However, the healing certainly seems suspect at times; they would heal me while over 95% while other group members were significantly lower. Their timing seems to be off, sometimes bursting at 4 stacks and others at 10 (for a substantial heal).

Edit: I also noticed my Death Grip cooldown not refreshing on immune targets. Just to confirm, the taunt mechanic still works.

In the Blues list of known bugs:
World of Warcraft - English (NA) Forums -> 4.0.1 Known Issues Sticky Updated 10/12/2010

Items
•Many items are losing their bonus armor.

I suspect the organ falls into this catergory and that the armor bonus will return once the bug is corrected.

Unless I am missing something here?

No, I think you are correct, my point was more what is better now. Most likely the organ will be fixed, I just wonder how long until that happens. The list linked was pretty extensive, so it is a bit of a concern to see they pushed this release with that many known errors.

On the plus side, I have to say that I do like the feel of tanking in 4.0. My run went pretty smooth, although it was vh and we were down a dps, so we were basically getting a constant flow of mobs.

Now I just got to remember that I have bone shield now.

i reforged whatever my highest avoidance stat was on every piece. think i lost about 5% avoidance and got DS heal up to 105%.
I'm seriously considering going diseaseless since it seems there is so much time doing nothing without a runic dump I don't want to waste time spreading diseases.

-20% attack speed is pretty easy to get nowadays. Any other DK in the raid will provide it if they're dpsing your target (they don't need a talent to get the full 20% anymore), because the dps specs definitely require diseases.

Also, while I'm sure they'll change things to make us play like they want, in the meantime, if something gives us an advantage now, we should do it.

I'd think it would be less for the additional talents and more for the additional healing/mastery shields.

I'm not advocating this as a full-time thing where you make a no-disease spec, I'm saying that Blood could potentially have two rotations:
no-disease (survivability rotation)
diseaseless (threat rotation) (or if debuff is missing)

I wouldn't want to give up diseases entirely at the very least because our AoE threat would likely suffer.

As we know Rune Strike is gonna be the dump that we can use whenever so we aren't going to have to worry about gaining threat from avoidance. On top of that there is no more ICC -20% debuff and can use some of our avoidance talents(I reforged parry on dodge/parry items and dodge on all dodge items) to test it out. Doing all my tanking items to mastery I lost around 5-6% avoidance and gained 108% mastery. While threat is a concern for now we still can hold aggro. My only question is has tests been done to see if our mastery stacks? Would be very sad to see a 11k+ DS crit get overwritten by a non crit. But Mastery is still very good considering anything less that a 6k overkill could save your life/buy one more swing timer for them heals to land.

Diseases can be a bit tricky at times IMO because of the way our rune regen works(which they are making faster). There are times when I cant use a global to get a disease applied to max out BB. This is where I see outbreak/pest/blood tap(maybe not in this order) shining. But honestly you should have at least 1 disease spread on your target(s) ideally plague strike(for BB Proc) until your unholy dk spreads his to get attack speed debuff.(TALKING ABOUT AOE) For single target there is no reason not have both diseases up. But again there are different situations where you might not have diseases on your target just to gain initial aggro but if you know a pack/spawn is coming you should be able to judge how many diseases you can use.

Also I want to know if Halion still has the avoidance debuff, If you guys get to him before me.

*spelling edit

Sorry, I may have missed some of the changes made recently so can you please explain the bold part about converting the unholy to blood rune ?
