item disenchant outputs

[khumash]

Tried to look up on wowhead database but it seems that the data is a bit out-dated. Such like some item can give more enchanting mats then wowhead database shows. Is there any other sites or addon can show the correct disenchant output info? Please advise, thanks.

Its random realy...80 greens give 1 to 3 dust or 1 to 3 lesser essences and at 85 its 1 to 5 dust and 1 to 2 greater essences...not sure when the essences go from lesser to greater but i think its lvl 84 greens.

Using Fizzwidget's Disenchant Predictor addon, which would normally on tooltips display the predicted results from disenchanting.
I have found that 318+ greens have been disenchanting into greater essences, particularly noticeable due to a text spam with that not being the expected result.
Was a hotfix which increased the disenchanting results, and the raising of the essences from lesser to greater at a lower item level than before may be part of that.
