Thanks for posting those numbers, that helps know what to shoot for. My Warlock is an Affliction Warlock, and all in all I would say I am very close.
According to that standard I am fine on health, +dmg (unbuffed over 700, and with fel armor over 800), and more than fine on +hit (with gear and spec, I have around 10% hit).
My mana pool isn't quite that large (it's at 8100), though to be honest I am not sure that is an issue. Affliction warlocks tend to regen mana fairly well throughout a boss fight. As an experiment I should go fight Dr. Boom (I think that's his name) over in Netherstorm and see how long I can fight him. I suspect I can fight him for a very long time. Still I will work on that.
One stat I fall very low on is in the crit (I have 10% crit rate). To be honest that seems very high. By that standard John Sr's warlock doesn't cut mustard, since Deedlyt's crit rate is around 13.7%. Affliction warlocks don't need crit to be nearly that I high I suspect, because we spend the majority of our time reapplying dots (which never crit). That's not to say that crit isn't important though, it is.
