Shamans now only get 1 AP from Strength, while also getting one from Agility. Streamlined the physical mail gear.

Exactly. Rather than advertising: I'm a shaman with X strength Y agil and Z int, you just say I have XX AP, that captures it all.

I thought there's a talent that grants you AP from intellect, but I may be wrong.

Although groups usually care more about your average DPS than your AP.

No I'm saying you'll have X+Y AP :)
Int to AP is a hunter talent: http://www.wowhead.com/?spell=34484

@Hendrata

You are correct. The Shaman talent is called Mental Dexterity (http://www.wowhead.com/?spell=51885), and 3 points in it will increase Attack Power by 100% of their Intellect.

Hunters have an identical talent, Careful Aim (http://www.wowhead.com/?spell=34484) which does the exact same thing for their ranged attack power.

@Nathanyel

No, its X + Y + Z (or Z, W, V as stated in the original poster) (Strength + Agility + Intellect) not just X + Y (Strength + Agility) because shaman also have a talent that converts intellect to attack power, not just hunters

Kitty druids have an insane amount of AP compared to other classes (between 7-8k), so using AP to compare across classes might be a bad idea.

Sigh.

Attack Power * (non-decimal Crit) * Base Weapon Speed * (1.Haste) * (%chance to hit, capped at 1.00). How about THAT.

4984 * 38 * 2.8 * 1.12 * 1.00.

Obviously that doesn't crank out an actual DPS number. But the value is fairly comparable between classes, although it doesn't factor in ArPen, because the various specs do various amounts of physical/spell damage, making it hard to judge how good it really is.

now that I think about it, that formula massively over-values crit.
