The thing to note is DS is a proc; I've seen entire boss fights where it never goes off. It's rare, but those times I wish I had been wearing Striker's for the passive rapid fire bonus. :P

My aimed shot casting timer bar always shows Aimed Shot casting at 1.8 seconds with rapid fire activated, and with a 40% haste, that would seem to be correct.

Am I missing something or is my mod just off?

3.0/1.40 = 2.142857...

40% haste doesn't mean 40% faster. It's 40% more hits in a given time.

40% faster would be 3*(1-0.4)=1.8, which would mean 3/3*(1-0.4)=1.66... -> 66.6% more hits. So, you are missing something and your mod is off. ;)

If you want an autoshot/aimed shot timer that's accurate, try BigTrouble. Last I checked, it was avaliable in the ACE SVN. /derail

To be honest, I'm not very fond of the 8/8 DS proc. I've had it proc several shots in a row on the Twin Emps (curse you magic immunity!) ... and had it quadrouple stack on random trash mobs (yay 2k+ autoshots?) ... and then had it not proc at all for an entire wing of Naxx. It's all in the random number generator. Maybe I need to sacrifice more expensive ammo to the random number generator gods.

Well of course you can argue controlled > non controlled boost in dps. But on the other hand, I think it even out in the end. Of course if the bonus dps from the non controlled is very small, then you can argue that controlled is better.

But on the other hand I wouldn't go for strikers to get a DPS downgrade( if enough hunters are pressent in a raid) just to be able to control my damage.

I realize that to do a more complete analysis of this topic one would need to know exactly when Expose Weakness takes effect given that a shot procced. That is:

If a shot that will proc lands at time 0, what is the earliest time that a landing shot will gain the benefit of the proc? Is it immediate or on the next tic?

This matters quite a bit, since if it's not till the next tic, which seems likely, then if any of your aimed/multi/free-auto shot proc it, you probably don't get the buff on any of those three shots.

Does anyone know?

I think the proc starts at the same moment the shot which proc it hits the target. But of course that shot doesn't beneift from the buff. But I haven't tested it

I havn't been able to narrow it down, either. I've had it proc while I'm moving forward to wingclip a mob that my pet has lost aggro on before. The only thing I can think of is that each tick of serpent sting can trigger it, but that's just inconsistent with other procs.

Are you the only hunter in the raid with it 8/8?

No but we are talking about solo-farming experiences :)

I've seen it proc off scattershot before(many times while mining in Darkwhisper Gorge in fact). Take that for what it's worth...

My time testing the proc (those servants should really be placed in a major city..) had me getting the proc from every direct damage ranged attack. Aimed Shot, Arcane Shot, Auto Shot, Multi-Shot, Scatter Shot. Not from stings, nor from other shots not dealing direct damage (Concussive Shot, Distracting Shot).
Hmm, this reminds me of something I have to test... can Improved Aspect of the Hawk proc from non-direct damage shots? And what if the mob is immune to the damage (Scatter Shot vs raid mobs)?
In other words: Can I force Improved Aspect of the Hawk to proc more by spamming specials while waiting for my other Auto Shot / Aimed Shot / Multi-Shots? Should be easy enough to test, just boring... as usual :P

Heh. If I'm in a raid situation with another 8/8 hunter and my PET just lost aggro on something, the last thing I'm going to be doing is running towards it to try and wingclip ;)

This occurance usually has me positively giddy in BGs. My #1 target for scatter is usually a rogue who has jumped me, and it seems about 90% of the time I scatter a rogue the proc would go off so as I moved into range I had a ridiculous amount of extra RAP against that target.

And the thought of the rogue on the other side of the screen going OH SH** is just too good. ^^

The thing you have to ask yourself with this proc is how many times have you seen it go off on trash when they have <10% hp and 90% of the proc is wasted. Maybe a solution would be to just change your armour in and out fight specific i.e. Trash stick with your non proc reliant gear then longer drawn out fights pop on your DS. It seems that if you rely on a proc for DPS your going to be left a lot of the time gimping yourself for those moments when it does proc.

We had a vaguely similar situation with our MT and Quel, he'd wanted it for ages and then halfway through BWL progression he finally got it and replaced spineshatter. Within 10 minutes of farming strat he decided that he didnt like a sub-par weapon which only became 'superior' on a proc. This epiphany had, he then re-equipped spineshatter and merrily carried on with quel languishing in his bank. It's almost certainly a play choice style, but stable constant bonuses to your dps seem to me to outweigh the bonuses of something which has a chance to improve your dps but no guarantee.

Something that helps the DS proc stick is getting people in the raid to quit sticking all the BS dots on targets. Rend and serpent sting are two. The DS proc gets shoved off the boss a lot if people are slapping everything under the sun on there.

There are guilds without debuff priorities? 0_o

I haven't cast a serpent sting unless we were wiping or dealing with inconsequential adds that died quickly since our first forays into MC. ("If I see one more serpent sting on that Molten Destroyer I am kicking every motherf**king hunter from this raid and all GS will be immediately DE'd!")

I don't think I've ever had a DS proc shoved off, and I recently witnessed a thing of beauty when a few hunters put on their DS sets again and we got it to proc 3 times on one boss mob. (Sartura was a sad panda.)

With that said, the above poster's sentiment is a good one. The DS proc is best utilized with a raid of hunters during a prolonged fight, IE boss mobs. During trash even if you can get it to proc the amount of time on it that will most likely be wasted would probably be completely one-upped by using individual pieces that contribute to a quick amount of dps.

Is there any relation to DS 8/8 proc against a 63+ mob instead of a 60? I would assume no, but I've gone through BWL runs where I've only had one proc on any boss, a few on Wyrmguards, and a ton on whelps. Single target vs. Multi-target could be the reason but want to see if anyone has tested this.

And does the proc have a high debuff priority similar to Hunter's Mark?

Not sure about the debuff priority, but I would wager no. Another hunter runs a mod in a personal channel that broadcasts when the mod goes off; it broadcasts when the debuff becomes presents and then reports again when it fades. Often times it states that it's on for a second later to say that it's gone. =/

As far as the buff itself goes, I've had some bosses immune and others flat out resist it. (Ebonroc and Onyxia seem to resist somewhat, and I think Ragnaros was the one immune? Not positive, I just remember the message. -.-)

You can no longer resist Expose Weakness. It's still an arcane "spell", though, so arcane-immune bosses are immune to it. Azuregos and the melee emp are the only two arcane-immune bosses ATM, although Viscidus might as well be for all the effect EW has on him.
