It seems that the haste effect has been changed on the current version of the PTR. (Keep in mind that it could be a test and it's not anywhere in the patch notes for the moment)

Melee haste rating has been nerfed, and it now requires 15.76 points of haste to get 1% increased attack speed. (Instead of 10.51 on the live servers)

Ranged haste rating calculation is the same as Melee.

Spell haste rating has been upgraded, and it now requires 15.76 points of haste to get 1% increased cast speed. (Instead of 21 on the live servers)

If you want to check your haste rating on both PTR and Live servers, you can use the two following commands :

Melee haste rating
/script DEFAULT_CHAT_FRAME:AddMessage(GetCombatRatingBonus(18))

Ranged haste rating
/script DEFAULT_CHAT_FRAME:AddMessage(GetCombatRatingBonus(19))

Spell haste rating
/script DEFAULT_CHAT_FRAME:AddMessage(GetCombatRatingBonus(20))

You should get a % value in your chatbox like in the following examples.

More nerfes?! Oh come'on  
When  is it enough    As if melee doesn't have enough problems. 

And yes as said above.. casters get a BUFF. Sjees.

Easy, it's called a wild copy past of the previous line. ^^

If this goes through on top of the windfury hotfix they should add a note saying to reroll wizard hat and robe.  Melee have to be higher dps/utility to warrant their inclusion in a raid or group given how far more convenient ranged dps is in EVERY setting.  Windfury was too good, and is still the best, but a horde of shit is not good enough.  The 2.1 patch changed core mechanics like cleave and delivered changes to several encounters large and small specifically to make the expansion more melee friendly because the original design was melee suicide.  Now the erosion of 2.1 begins with 2.2?  I'm beginning to wonder if the developers actually play melee.

More of the same from Northrend?  Mobs that instantly and without warning give the tank a 10k per second aura of death to rogues sounds like the perfect "challenge" to preclude taking any melee dps to said encounter.  Sounds outlandish (haha funny), but thats a Northrend scaled version of what Omor in Heroic Ramparts did, and post-nerf still clings to pretty closely.  How about mobs that have an auto attack for 5k with a whirlwind that goes off in 1 second (5k damage), snares, and fears?  What if we followed him with an NPC that heals, cleanses, and lays down an 800 point consecrate under himself constantly?  Thats Heroic Durnholde, probably the single least used heroic.  And that is its current inception, not "pre-nerf".

There is no such thing as "ranged haste rating".  Haste rating applies to all physical dps rounds.  So hunters will be affected negatively.

I hope this doesn't go live, but regardless of this potential nerf several encounters are still mad queer for melee participants.

You might want to reread that, Spell haste has been upgraded not nerfed.

People like you are really not bright. You know any nerf to any class will nerf your raid therefore will nerf you right?

Still doesn't make Quag's Eye very worthwhile IMO, heh.

Thats bullshit.. BT items giving to much haste? Nerf those items then. My DraginSpineTrophee is a much needed tool to stay near the top. Nerfing that hurts no matter how little a nerf it may be.
