[Keres]

Actually iLvL was invented by players. Blizzard simply added the feature because so many people used an add-on to display a numeral value based on gear

This is not true at all. Item level (as in, a coefficient that determines what sort of stat budget a particular item gets) has been in WoW since day one, and evaluating people based on their average item level has always been possible (though the "average item level" wasn't displayed in the UI until several years in). Even the weakest piece of gear in the game has an item level attached to it, and it simply determines how many stat points (and/or weapon damage) will be on that item. Vanilla WoW had a lot of instances where lower-ilvl gear was better than higher-ilvl gear, but that was mostly due to poor itemization (all 5 core stats on most pieces of Paladin gear!) rather than anything inherent to the game design itself.

What you're thinking of is "Gear Score," a player-made concept where a certain addon would take your item level, enchantments, gems, and other parameters into account and combine them all into one aggregate score.
