GearScore calculates an overall item level score for each player’s gear and shows it on unit frames and in tooltips, making it easy to quickly estimate how well-geared someone is for a dungeon or raid.
How to use:
Install and enable the addon, then hover players or inspect them to see their GearScore in the tooltip and on their frame; options such as display style and color thresholds are available in the GearScore section of the Interface → AddOns menu (varies by WotLK build).
