Disenchanting probabilities

[Bit]

Enchantrix uses a static database based on user-provided statistical data about disenchant probabilities.
I'm curious if this is actually necessary/they did this just because they didn't know any better at the time or if this "simple" formula: http://wowwiki.wikia.com/wiki/Disenchanting_tables also applies to vanilla.

[Roadblock]

I don't know, I'd always used Gazmik Fizzwidget's Disenchant Predictor which was using such a formula

The main issue in vanilla was item level is not directly exposed in the api.
You can make an educated guess (for example "requires x level" blues translates to "x + 5" internal iLvl) but not all items have a level requirement (most quest rewards don't for one)

Then item qualities come into play, not all items are disenchantable etc, that's probably why Enchantrix took a statistical approach.

Edit: Here is his latest vanilla version

Oh, right, thanks, wasn't thinking of that. How reliable is the GFW addon formula? Maybe I'll adapt that for Aux.

It's pretty good for its stated purpose.
