http://us.battle.net/d3/en/calculator/demon-hunter#aRjXVT!Yce!ZZbZcZ is my current build in act 2 inferno. @ Espy, not using nether, but i find myself spamming my frost ele arrow even in single target, hungering mainly when im lacking hatred. SS/prep as a lot said befoire, is a must in inferno. Vault left my build around early hell. The immunity is just too good to pass. As for the passives, hardly any other are somewhat good, there are a maximum of about 6 viable passives total depending on the build.

Rapid fire with fire support always spawn the full number even if theres only 1 enemy

Update on current build (now lvl 47, mid-act 3, nm)

Ferrets are for fun, but I just love em and I can spare a skill since ive only been mainly using caltrops, hung arrow and multi shot since the beginning of nm act 3.

Oh god, thank you. Oh god.

In game? Didnt find any way to have multiples abilities from the same catergory at once.

@Zaka, youre using multiple spells from your hunting branch, i.e. preparation and vault, either not possible or you managed to find a way to do it.

Archery and steady aim. Usually would get cull the weak but im running with tactical advantage because i can spare it and it makes my run through nightmare faster hah

Im currently using hungering arrow with scatter shot, chakram with razor disk (which is surprisingly the best aoe hatred-cost/dmg wise ability ive come accross yet), torturous ground caltrops, tumble vault, and the 2 others im not really using yet, didnt find a good place for them (usually spike trap or evasive fire in 3, and multishot in 4)

I personally didn't like fan of knives, as an aoe ability, the cd is pretty high and not worth it. You also don't have any slow, except the 60% from the 10 sec cd FoK, and it def wont be enough. If you really want Impale, i'd suggest the Impact rune, mainly for bosses. Shadow power is fine, yet id rather pick the caltrops over it. You'd also lack a spammable AoE ability, like either multishot, cluster arrow, chakram or elemental arrow. Out of them, my 2 favs are def multishot and chakram. Also, brooding is pretty damn bad, id suggest archery over it.
Yet, this is just my opinion and im just level 37 as of now, and you'll have plenty of time to test it out yourself.

Cull the weak is fine, yet I tend to like archery more over it. and as far as ive tried beta-wise entangling shot was pretty weak, even with the slow, rather get a higher damage hatred builder, with another ability which slows, else it just looks like a huge dps loss, and like sibilant was saying, your primary move is a lot of damage

I always have the same thoughts about the explosive dh build, which is that it should always include grenades as the main hatred building ability. Why? you basically rune it to give you 6 hatred + get grenadier which put it at 8 hatred per grenade + reduce the cost of cluster by 10.

Also not a big fan of MoD and sentry, but for those, we'll have to further test 'em when its out.

I also do think its lacking a bit of single target for hell and inferno, but we all have yet to try it, so who am I to say this. Anyway, i also think that replacing Vault with Evasive Fire runed with displace. More damage, 5 less yards, mostly infinite backflips. And as I said, those are just pre-game thoughts. (without being an a-hole grammar nazi, remove the i from caltrops.)

Definitively is, and if you have extra money, it's possible to get the digital, enjoy D3 as soon as it comes out, and then upgrade your account to CE when you get it.

It has pretty much been always available, the main reason why no one ordered from there is because of the shipping time. They ship on 15th but estimated time for me was around 20 ish.
