Unfortunately you can't. Not on PTR at least. [Frozen Bonespike] e.g. i could only reforge 26 spirit to 26 haste.
Don't have any Bluepost about it, but it seems you can only reforge about 40% of the "useless" stat. But i would say, we will need all of theese nonset items with spirit aka hit on them, since t11 doesn't have any on it.

edit: Hyperspeed Accelerators got slightly nerfed at PTR down to 240 haste for 12sek, can't say if it is intended.

It's not like you can totally ignore spirit regardless. There are no more hit talents in the game from what I understand (at least that you can obtain from other classes/racials.)

In order to obtain 17% hit you are going to need 2612 spirit on your gear. If none of your tier pieces have spirit... then you're going to pretty much going to need spirit on every non-tier piece to even get remotely close to that. You'll probably even have to use a hit trinket.

And where in that post does GC state they are changing spirit/hit to devalue as tiers go on so that you need more of it? I didn't see that.

I imagine as tiers progress you'll then start reforging spirit off gear for other stats because you'll be at the cap.

He may not have said it in that post, but it has been stated on multiple occasions. It's a way to circumvent the problem of not having the opportunity to put much hit on upper lvl items due to everyone being capped.

Rather disappointing. On the upside, I've heard (not yet confirmed) that Engineering tinkers now stack "in addition to" and not "in replacement of" other enchants. So 28 sp + Hyperspeed on gloves would be workable. Again not confirmed yet.

That number seems way off, Graylo over at graymatterwow.blogspot.com said he found and is almost sure the number will be 1742.

Which appears to be the case based on mmochampion's datamining. It means we have 13 slots (if we use 4/5 tier pieces) to reach the hit cap. Now, based on an item like this: Robes of Forgetfulness - Items - Sigrie, I really don't think we're going to have any problems reaching the cap.

EDIT: Though it does look like Blizzard is rolling healing/dps leather gear into one package, which could end up being poorly itemized compared to cloth items.

Which is the opposite of what the problem is (or half of it).

Tierpieces have 0 spirit. To reach hitcap, everything else must have hit/spirit.

And until you get tierpieces you will prolly have way too much hit, at least if you are going to try to get the all-leather-bonus.

It's a solution(the hit/spirit thing) with a lot of problems.

Poorly itemized how? When you see spirit on an item just think "hit" rating. They are 1/1 conversion and worth equal amount in ilvl budget. There will be plenty of haste/crt/mastery items on cloak / ring / trinkets. I really doubt you'll have so much hit / spirit on some random gear that you'd complain that you have forced spirit on belt / bracer / boots (these are the only 3 items you'll be forced to wear with spirit). Your tier gear doesn't even have spirit or hit. I'm almost certain Moonkins are going to have to reforge a lot of their gear so they have spirit/hit.

Except that is where reforging plays a role. It makes a lot of breathing room.

Raiding in tier gear (reforge spirit on)

The only reason bosses are scaling is because of the item budget issues of Icecrown. Just to point out one example: several items (staffs particularly) had so much hit on them that they were completely and utterly worthless to everyone. No one needs 120 hit on a single item in Wrath. This system of boss scaling was designed so that the would have more room for those stats to actually be useful.

Personally, I think it's kind of a poor excuse (what is the big deal with giving people the stats they want anyway?), but at the same time you can't really blame them. There are only so many stats around, so this setup is an attempt to make certain stats more valuable by removing the standard cap for all raid setups.

I can confirm that this is true on the current build on the PTR, and I would assume beta as well.

edit: However, it seems to be slightly bugged, as you must apply the enchant yourself (I did this via vellum). When I tried to have an enchanter do it via trade he said he received an error telling him he needed to be an engineer.

PTR Build 13082 fixed the Omen of Clarity bug (at least for Balance). I expected my sustained dps to drop over 1k after that fix but I just sustained 14.2k for right around 1 hour / 50 million damage. I wanted to get a good sample size but, especially after 4 hours of raiding, my hands hurt now Couldn't help myself -- was antsy to see what final numbers looked like as I think we are getting very close to a 4.0 build at this point.

Anywho, log linked below:

World of Logs - Real Time Raid Analysis

Interesting numbers:

Nature's Grace uptime: 60.5%
Lunar Eclipse uptime: 33.3%
Solar Eclipse uptime: 31.2%

I was sitting at 3735 sp, 29.86% haste (979), 17.5% hit (capped), 49.98% crit (1362) and default 8 mastery. Mix in some heroic Phylactery and DFO procs, rep ring procs, and Hyperspeed gloves as well. Prime glyphs used are Insect Swarm, Wrath, and Starsurge. Major is Starfall.

Aren't we in a better position than clothies due to hit from Spirit? OK our Tier gear has none at all which leaves boots, bracers and belt but there is also the possibility that we could pick up a healer cloak, rings and/or weapon if we need too and we still have the option to pick up specific DPS versions of these too? Don't personally think we will need hit trinkets as much as the clothies will.

Not entirely sure why people are stressing so much over gear at the moment honestly with the options this change has opened up for us?
