So I did some research on Green lvl 60 items to find out the max possible Stats for them,
And according to my research, the max possible stat for a single item at lvl 60 would be 29.
However this item showed up a few nights ago being sold in world chat on the PvE server

This item has more Ranged Attack Power than Armor and the usual conversion for attackpower from a stat on a green item is 2:1.
ie: Green Strength item has 4 Str, Equivalent lvl Green has 8 Attack Power, (and yes there is usually a 1 point variance on items so 3 Str, and 6 Ap would be equivalents as well; There also seems to be a 2 point variance on items that are of every 10 lvls, ie, I have seen lvl 40 chests with 17 Stam and +19 Stam)
However given that the assumed maximum of a lvl 60 Green single stat is 29, to keep it relevant, 29 Agility which would translate for a hunter into 58 Ranged Attack power, I don't understand why it would 9 Attack Power higher at 67.
A person on the server was trying to make some argument to me that it was taking into account the possibility of a hunter have the +25% Agility Talent and redistributing the extra Attack Power to all who didnt have the spec and that Attack power items often outweighed the 2:1 ratio on the principle that Attack Power gives less as a whole, however after years and years of playing this game I have yet to see that be true except for this case.
