BA nerf is on base damage. Actual damage nerf is like 3~% if my math is good.

According to FD.com the nerfs means about 2k (from 22,5k DPS on live).

Into the Wilderness (passive) has been reduced to a 10% Agility increase, down from 15%. Don't forget about this also. *Ouch*

MM did get a buff, they just aren't showing the previous 4.0.6 patch notes on MMO Champ. Chimera Shot and Aimed Shot both got a buff. Kill Command also got a buff.

According to a Blue Post I saw they did fix the haste regen problem and somehow Cobra Shot and Steady Shot are also scaling with Haste. I don't exactly understand that last statement, so if anyone could enlighten me I'd love to read your wisdom. How do CoS and SS scale with Haste now and what does that even mean?

It is a mistake. SS and CoS are lumped together with Slam, which doesn't scale with Haste. If they hadn't mentioned Slam it would be reasonable to expect it was some extra scaling or sorts, but Slam is going to behave differently from now, yet it is hard to imagine the focus shots changing much. And from what I have heard from PTR people, they are exactly the same. I pray that those people are wrong.
In conclusion, this comment is in line with the old Agi = 2 AP in Wrath by GC, and isn't entirely different from something like "Explosive Shot now ignore armor". Basically disregard it. It is however a little concerning that it is considered a counterpoint to the heavy nerfs.
At least the HP bug is being fixed, not that the eventual change is very big (most likely more important for melee classes), but they have finally given us the confirmation that it was wrong.

A lot of people run around with their hands in the air claiming that Explosive Trap is now better single target DPS. I think they read the reduction as a full 25%, and not base damage. It should still be comfortably ahead in total. The main worry is if the more LnL procs can make up for it. Regardless of BA being more damage, the fact is that it is still talented. It should be a clearcut winner, especially considering it is a 31 pointer, it should be more than a few DPS added. People should want to pick it. It is alright that Explosive trap is there for those that don't want BA, but competitive?

I did expect some sort of Serpent Spread nerf, but this one seems skewed. Multishot is decidedly poor on it's own, as evidenced by the other two specs. Which is still a problem for them I might add. Possibly we can expect a buff to multishot in one of the next builds. As noted by others, the impact could be lessened a fair bit if the game is somehow a bit intelligent and applied serpent stings to unstinged targeted when we multishot. In that case I can see this nerf making some sense.

A lot of people at other places are yelling BM nerf of 3.0.8, but this isn't anywhere near that. Besides, this is only the second build. Seeing what was put out in the first, combined with this, the picture if getting a little clearer, but as we can see here, it isn't crystal clear yet.

That's interesting. Could you please explain where the extra Arcanes come from?
So far I understand we have two possible alternatives:

1) We use 3 shots-> ES rotation. The 3 shots are typically 3 cobras. Sometimes one of the cobras will be replaced with BA or possibly an Arcane (though it's debatable if it's really a gain over cobra). Haste does not significantly increase the number of Arcanes because even if you finish the third shot before ES comes off cd, you just wait a short time until it does, so the focus gain remains unchanged. Beyond 757, we tend to treat haste as junk, as it only affects our auto-shots and pet auto-attacks. Rather than trying to increase the number of shots, we try to increase the damage of those we do shoot by stacking crit and mastery.

2) We use 4 shots -> ES rotation. We don't wait for ES to come off cd and always start the 4th cast regardless. This way we get many more cobras and the extra focus flow also allows us to replace at least some of them with arcanes. We conciously delay our ES however, and fire fewer of them over the course of the encounter. Haste remains a very powerful stat for us (probably equal to crit and superior to mastery) as it shortens the delay of ES. However, haste itself still does not increase the number of arcanes we can fire. The faster focus gain coming from casting Cobras more quickly is immediately consumed by being able to cast ES more quickly (as it's "natural" 6 second cd is no longer the limiting factor).

So, in either scenario adding more haste should not significantly affect the frequency of Arcane Shot, though admittedly in the second case you are going to shoot many more arcanes and also it makes sense to keep stacking haste if you go for the second rotation while it's completely pointless in case of the first one. These however, are just two independent side effects of choosing either 3 or 4 shot rotation and have nothing to do with any direct correlation between haste and being able to shoot more arcanes.

I have ran into a problem which I couldnt find an answer for searching these forums. But on the analyzer, if I reforge all mastery slots to haste... it puts me at 1000+ haste rating, and a big increase in DPS. If I then go in and change some of those "mastery->haste" to "mastery->crit" it lowers my DPS significantly. I tried removing Arcane Shot glyph, and putting in the serpent sting glyph(thinking maybe I was getting more glyphed arcane shots in with the extra haste) but it still shows the haste > crit passed a 750 rating.

Very interesting. I'm guessing either increased effect of the cast time on just cobra/steady shot or some kind additional damage co-efficient.

@Perolord. Other people do need to move yet, but do they move as much as you? Good positioning at the start of the fight and good use of Fox and stutterstepping while keeping ES on cd while you do all this will increase your dps massively while moving. Comparing your HC5 dps to raid DPS isn't a good idea either as they arn't comparable.

My best guess is to make haste also restore more focus with each cobra or steady shot cast.

I thought of that, too, but that would result in some serious double-dipping, since 10% more haste already results in 10% more focus regained, if you're chaining cobra/steady. Of course, as far as SV and BM are concerned, one has a rather strict five second window, so often times more haste might not result in more focus through focus shots.

MM, on the other hand, has a nine, or even ten, second window - so it becomes less important to fit everything in there perfectly. So for MM, haste would get awfully strong - I suspect that it already is, though, which wouldn't make adjustments to our haste-scaling very important as soon as all specs are roughly on equal ground, because desiring different stats would also add a different feel to the specs then, where MM had a more spammy nature, SV a more hard hitting one.

So the effect is basically doubledipping? You didn't have any sort random focus generation happen (just to be sure)?

Previously all Hunters got 17 focus per cast of a focus shot (and with Haste this was achieved faster), but now the focus granted by shots increase too.
Hm, I get the feeling that it won't really impact Survival all that much. Aside from having slightly less of a pushback on Black Arrow usage.
