With a reaping build you'll find you have extra GCDs. Thats usually where I throw my BT/BS in.

IE: PS - IT - BS - BS - SS - DC - HoW SS - DC - SS - SS - DC - DC [BT/BS]

In your next rotation your extra GCD would be between your [2nd] and [3rd/4th] SS's.

At least this is where I am finding my best luck, since if you do it before your PS/ITs you can pull an extra DC before you restart your rotation.

The best is for non-burn fights to renew it every time you're away from the boss. IE: on Rotface25 when you get Mutating Infection, renew it as soon as your slime is absorbed by the big slime, that way you don't spend charges on a useless ooze. The run time back to the boss should be sufficient to regain that unholy run without using blood tap... Now you can blood tap on something else useful.

I haven't done the math but my suspicion is it's because of 2pt9 and Unholy Might. I wouldn't bother replacing it with PS until 2pt9 was broken, unless you somehow managed to time it exactly so that blood tap was only used while the 2pt9 proc was on its cooldown.

The usual BS should be enough for 2pt9 to proc. I usually save BT for bone shield incase it falls off, but I do BT/BS in the initial rotation to make sure 2pt9 proc was up so I can maximize AP with gargoyle. I guess BT/PS is a good idea too.

The primary reason why you BS as opposed to PS is due to (the potential of) a lost disease tick from clipping. It depends where exactly the PS falls as to whether or not you actually lose one, but considering the two abilities do near identical damage to begin with, and that even a fraction of a chance of missing out on a disease tick would easily cover the minor gap, it's really not worth using it on PS.

PS does deal more raw damage than BS though, yes.

3% dmg done doesn't equal 3% dps. The following math is simplistic and not entirely correct but it gives the idea:

Assume 9k dps single target over 5 minutes ( 300 seconds ) with 294 seconds uptime on a static fight.

9000dps x 294sec = 2 646 000 damage done under the buff

2 646 000dmg x 0.03 = 79 380dmg coming as a result of t10 4 set

79 380dmg / 300sec = 264 dps for the fight as a whole

As you can see, the more damage you do, the more damage the buff does. So you can see that it scales every nicely with gear. As 9000 dps is a reasonable assumption in ToC/ToGC 25 gear we'll take Consider's AP/DPS values:

264dps x 1.56 = 411 AP

The discrepancy from the table is due to the simplicity of my math.

I feel somewhat sheepish asking this, but searching the forums has left me more curious. Regarding bloodtap macro's, I've used both the macro from the OP and a similar one without the /stopcasting command. In both cases I need to spam the button in order to have Bone Shield cast, despite BT being off of the gcd. Some of the posts I found say that a single button press will cast both BT and Bone Shield, while I've never been able to do that; this results in my rotations being thrown off unless I replace a Blood Strike with the macro (non-reaping build). It seems that while BT is not on the gcd, the rune activation takes some time, as using the macro with all runes up results in an instant Bone Shield via unholy rune. My latency is ~60ms, if that has any bearing in this.

Which is the expected behaviour for the macro and how are you incorporating it into your rotations? My assumption is that the functionality I am seeing is likely much easier to incorporate into a reaping rotation with both death runes up, prior to the SS, so perhaps I should just switch to a reaping build.

BT has a small delay until it kicks in. That's why I use the following macro:
#show Bone Shield
/cancelaura [button:2] Blood Tap
/cast Blood Tap
/cast Bone Shield
You can spam it to cast Bone Shield and then you just have to right-click it to get rid of the BT buff. It worked out as the best solution. After casting Bone Shield you have plenty of time for clicking anyway.

If you look up Tuskarr's Vitality on Wowhead, you would know that the enchant provides the same runspeed increase as having 1 point in Improved Unholy Presence.

I believe he's more looking for the comparison between 32 AP and 1 point in Necrosis.

Taking a look at my own log, necrosis provided approximately 98600 damage over 294 seconds, or 67 DPS per point. Using Consider's OP values for DPS:AP, that turns one point of necrosis into 67*1.59=106.53 AP.

As a side note, Cat's Swiftness is a superior DPS enchant if you decide to go with a movement speed enchant.

If you want run speed (seems like a good idea), it is better to put run speed on boots instead of Icewalker than spend 2 talent points.


Regarding the change in mechanics, since the Shadow part of SS does not count as a melee attack anymore, my FC went from 83 to 76, so that means Strength stat weight would be a little less.
