Agility equivalence points

Agility Equivalence Points is a method to convert the value of item attributes to compare them in terms of Agility points.

Rogues
Based on the Forum Discussion initiated by Ming from Lightning's Blade.

Formula: 1 Agility = 1 Stamina = 2 Strength = .1% Crit. = .2% Dodge = .13% Parry = .13% To Hit = 2 Attack Power = 5 Daggers = 4 Any Resistance = 5 Health/5 Sec. = 50 Armor

For Rogues, two other formulas are useful:

Sinister Strike AEP Formula: .33 Avg. SS Dam. = 1 Agility = 1 Stamina = 2 Strength = .1% Crit. = 5 Defense = .33% Dodge = .2% Parry = .13% To Hit = 2 AP = 4 Any Resist = 5 Health/5 Sec. = 50 AC

Off Hand AEP Formula: .17 Off Hand DPS = 1 Agility = 1 Stamina = 2 Strength = .1% Crit. = 5 Defense = .33% Dodge = .2% Parry = .13% To Hit = 2 AP = 4 Any Resist = 5 Health/5 Sec. = 50 AC

Hunters
For the Burning Crusade the formula for AEP as it pertains to Hunters has changed somewhat. This information is based on WOW and has only been partially validated in play.

Formula: 1 Agility = .552 Crit Rating = 1 Attack Power

Paladins
1 agility = 0.04% of dodge (if you had 50 agility you would have an added 2% dodge).

Warriors
For Warriors tanking in a 5-man party: 1 Agility = 2 Strength = .33 Stamina = .25% Crit. = .07% Dodge = .07% Parry = 4 Attack Power = 10 Armor = 0.25 DPS = 4 Shield Block = 1 Weapon Skill = 4 Health bonus

Twinking notes
Noticing the link to shadowpanther.net, it might be worthwhile to point out that the Crit from Agility is not as powerful as it is later in progression. A top tier level 19 Twink (as of 2.3) has white dps of around 35-40 (higher if they sacrifice HP) for their Main Hand weapon. Given that, for physical damage, 1% of crit will increase DPS by no more than .3 to .5 at that range. 1 point of Agility (for a level 19 twink) may be worth closer to 1.5 AP, as opposed to a full 2. This would mean that items such as would be worth closer to 12 AEP (perhaps surpassing the  with its 11 AEP)

This would not affect just AP, however. The AEP value of Agility itself (and also Crit Rating) scales with 2 things: diminishing returns as player level increases, and DPS. On the other hand, Strength, Stamina, and AP all add a fixed gain.
