If you're using an ArP setup, you need the extra ArP from the offset pieces more than you need the 4p bonus.

First regarding the 900 ArP. Yes, stop @ 569 unless you can hit the hard cap and drop Mjolnir (not currently possible). No one said 4 piece is bad, but consider the extra ilvl 239 pieces you can use breaking the 4 piece produces better stat allocation and more stats, enough to override the avg dps gain of the 4 piece.

Edit:
The other problem is hit! How do you make a build without wasting talent points, that drops your hit as low as possible. Here's the short list:

Conqueror's Scourgestalker Spaulders: 43
Conqueror's Scourgestalker Tunic: 57
Frost-bound Chain Bracers: 33
Conqueror's Scourgestalker Handguards: 43
Skyforge Crossbow: 23

Total: 199

That is the lowest I can make using BiS gear and 4 piece making the 3rd point in FA worthless. What do you do with this floating point to create a spreadsheet dps gain? Since this point becomes worthless, and you gain 2 ilvl 239 pieces by breaking the 4 piece, grabbing a better stat allocating ArP piece for the 3rd non set piece (Mantle of Fiery Vengeance) becomes a better approach.

I think you only gain one ilvl 239 item, the [Legguards of Cunning Deception]. The [Gloves of the Steady Hand] you are wearing anyway, and the [Mantle of Fiery Vengeance] is only 226.

Arp soft cap can be achieved without sacrificing 4set. I think im missing something. Why would you pass it up?

Hi I'm a new hunter at level 80 and my dps is very very low.. and i don't know what the problem is. I'm wondering if its my rotation or my gear or specs.. maybe glyphs. The World of Warcraft Armory that is my character and i was hoping you guys can tell me whats wrong xD. I'm currently using terrorshaft arrows and my rotation is: serpent sting -> chimera shot -> aimed shot -> multishot -> steady shot. And my dps comes out to 1300 at best :x please help me =]

Don't use Terrorshaft Arrows. Use [Saronite Razorheads].
You can't use Multishot after Aimed Shot, because they are on a shared cooldown.
You're lacking LOADS of hit. You have only 44 (1,34%), while you need 8% (of course if you are not raiding, this doesn't concern you.
Get more heroics gear. Read the forum for other tips and try to figure out the rest by yourself.

For the fellow M.M. hunters out there.I had got the hit cap the the other day and re-gemed a Pristine Monarch Topaz with a Bright Scarlet Ruby but then changed it to a Brilliant Autumn's Glow and ended up getting more atk power from it then i would a Bright Scarlet Ruby, so im wondering if with intell that we get more atk power?
I would be pleased if I would get a reply.

From Armory I assume you're talking about your gloves. That's the only yellow gem that you have. When you took out the Pristine in place of the Bright, you deactivated your meta gem (losing 21 agi). When you took out the red (-32 AP) you gained 16 AP via Int from Careful Aim and 21 AP via the reactivated meta. Overall a 5 AP gain besides the extra crit, mana, and +3% crit damage multiplier.

As an ArP stacking MM hunter, Grim Toll procs boost my dps dramatically during the proc, so I'm wondering why I'm not seeing ArP Stacking Hunters stack both Grim Toll and Mjolnir Runestone... I'm assuming the Procs share ICD's?? Just wondering the mechanics of these trinkets and their effects on each other when using both. (Noob question, sorry :S) Also, another noob question - sorry, just to clarify... What's the ideal amount of ArP for stacking ArP as MM, and what is ArP's hardcap? I've been reading page after page of this thread and have probably skipped over it somewhere. Thanks for the help.

Yes, however the stat allocation is good enough to create a considerable difference in dps gain. Legs (Crit Haste AP) and Shoulders (Hit Haste AP) are less desirable then Crit AP ArP which are found on their counterparts. Since haste is your least desirable stat due to rapid fires and quick shot procs, it is devalued to near negligible levels. Once you do reach the ArP Soft Cap, gemming Agil results in the larger dps gain, making your stats only ArP, Agil, AP, and Crit on every piece of gear, erasing haste entirely.

Please refer to the best dps thread for the numerical specifics, as that discussion does not belong here.

I just tested it myself and Grim Toll and Mjolnir Runestone does NOT share cooldown, if you're lucky you can get them to proc directly efter eachother which ofc is great but you can also get them to proc at the same time, this means that the second proc is totally wasted if you're at the ArP softcap with your passive ArP.
So you're probably better off going for another trinket like Greatness.

The ArP hardcap lies at 1231 ArP and the amount you want to aim for with an ArP trinket is the softcap which is 556 with MJ and 619 with GT.

But in the next patch, one can re-equip one of the trinkets right before the fights starts, triggering the ICD and hence making sure that they won't proc at the same time. Altough at this present time, I can't figure out a way to make this happen.

I've been an avid reader for sometime and I just have a quick question. I'm spec'g MM tonight to ensure we have the 10% AP buff while our enhance shaman is away and figured I would give ArP a serious look if my gear is managable enough at the moment. I currently don't have BiS items, but what we're looking at stat wise is 570 ArP, w/ grim toll, and 269 hit rating. I normally run SV so all my gems are pretty much 16/27 agi. Since I'm over the hit cap, should I toss points into IAS or is my ArP at a respectable lvl where I can ignore it's use, except for situational, ie waiting for CDs or moving?

Thank you for any help in advance.

Didn't look at your gear, but from those stats I would advise taking my MM spec, as I am the only hunter in the raid and in a similar situation. Since you have grim toll you may want to change a couple of gems to get your ArP to the 600-620 range. You should see dramatic results over your Surv spec doing this, usually in the 1k range.

Looking at my gear would only show you my SV spec and current raiding gear. I've managed to get a couple pieces here and there that have more ArP than my current gear I have equipped, but like I stated earlier, it's by no means BiS. Getting from my current ArP of 570 into the 600-620 range would be no problem at all. My biggest concern is mana issues, seeing I have virtually none as SV and then giving up on the spec too soon. The hassle of regemming everything is something that is inevitable.

Just updated the first post. Please PM me if you want anything added.

I've tested both on the spreadsheet and SS glyph comes out 11 DPS higher than KS glyph.

I don't believe things are as black and white as that though - SS is only good when stationary which isn't that often - KS can be used always but then that depends on the amount of time a boss is <20%.

I'd imagine this is a standard issue for most MM hunters but which would you prefer? Both would get buffed by ArP, so I don't think it would matter which MM spec you're going with.

I believe the advantage of having the KS glyph is on bosses which involves add handling, mostly thinking of Yogg-Saron where Kill Shot is used frequently throughout the entire fight.

So the answer to which glyph is the best depends alot on the fight.

why dont you use Trueshot Aura in your spec?

Another hunter probably has it or they always have an enhance shammy in the raid which makes the point in TSA wasted since it doesn't stack with unleashed rage.

It's always good to sync your specs in the guild, just like with TSA it's also good to have one hunter spec into Imp hunters mark and even better if he also has the hunters mark glyph.

and what about Arcane Shot, it isn't useful anymore?

I agree it depends on the fight, but SS glyph will perform better on more than a fair share of the current content.
