Rough (*very* rough) ballpark figures (based on the ShadowCraft model and whatever near-BIS gearset I happened to plug into it the last time I was using it) - basically, don't use this for more than rough order of magnitude:

I was discussing what to do when running into the "ceiling" of the energy pool, I understand how it works. The question was if the damage from envenom outplayed that of rupture (ignoring the envenom buff, because it is up 100% at the time regardless). You answered it in your explaination, but the rest was unneeded, there is no issue between clipping or pooling, because I'm at 120/120 energy.

That's per point.

So is this:

(Usual caveats about this being a very rough estimate, blah blah blah)

Does anyone know how to set-up Power Auras to only announce getting the damage buff (not the transfer threat buff) from Tricks of the Trade. Or, better yet, is there a mod that alerts you of that 6secs of 15%/20% damage buff?

I was curious how much energy affected energy regeneration as Sub. I believe sub is the lowest passive energy regen outside of energized recovery talent (could be wrong, so don't quote me on that!). Is there a certain amount of energy we regen per %? I apologize for such a plain question, but I have spent endless time trying to find info on this and I have yet to yield any. I also apologize if it is blatantly posted somewhere and i missed it! Thanks in adv.

I bet a lot of us will be interested in that, that video can single handle lot of questions about the encounter.

In a similar vein, I occasionally find myself in a situation where I've been pooling energy waiting for the envenom buff to drop with 4cp on my target, ~3s on Rupture left, and I'm approaching 90-100 energy. In such a situation I would envenom to utilize my cp and follow with a mutilate to dump energy as per normal, but then my rupture falls off and I'm left waiting a few seconds to generate the energy for another mutilate so that I can reapply a 4-5cp rupture. So my question is, how detrimental a damage loss is to be expected from not having rupture on my target for 2-4s (keeping in mind I've also lost Venomous Vim procs)? Alternatively, would it be better to apply a 2-3cp rupture immediately following rupture dropping off instead of waiting for the energy for another mutilate/rupture?

The short answer is that it appears to be better to rupture, regardless of size, then sit around with Rupture down. This has been hypothesized before, and we still need good modeling for it, but in terms of very rough estimates of the damage "cost" relative to the theoretical ideal of always having a 5pt rupture up:

Leaving rupture down for 1 second: 3.4k damage.
Using an undersized rupture: 450 damage per combo point.

That is: using a 1pt rupture is, damagewise, about the same damage loss and letting it drop entirely for half a second. In short: it currently appears that the right decision for rupture is to refresh it on the first GCD where you have combo points after the old one drops. And you should plan to always have combo points.

For those wondering: I do plan to update the ShadowCraft model to reflect this behavior. However, modeling it is harder than you might think, so it might take some time to get it working.

Also, to update the numbers that you quoted with more accurate numbers I computed while working this out:

Clipping one second of envenom buff: 1.4k damage.
Capping energy for 1 second: 8.9k damage.
Wasting all combo points from 1 Mutilate: 19.3k damage.

This is still numbers referring to one particular gear set; don't take these as exact numbers that apply to your situation. However, the general principals - it's better to cap energy for 2 seconds than to Mutilate at 5 CP, and it's better to clip the entire envenom buff - twice - than do either - are probably generally applicable.

I think I read somewhere that it's okay to clip Rupture with 2 seconds to go or less, as that clipped 2 seconds will be added onto the new Rupture. Is this an accurate assessment or did I misread.

I tested it today with glyphed Rupture (I simply counted rupture ticks with and without clipping on last 2 seconds). I did not loose any ticks by clipping it on last two seconds. That said, sometimes you may be unable to reapply rupture if your old ruppture is still active and you get "more powerful spell is active" error.

SnD in PTR:

I was wondering: if the way slice and dice is working on the PTR (effects Haste) is actually going to make it live, would this (plus the buffs to combat in 4.0.6) make combat > assassination for raiding?
