there used to be a fubar plugin called gearratingfu and it gathered the average Ilevel if everyone's gear in range in your raid/party and displayed them in a nice drop down from fubar. it was nice because it gave a basic idea of your group make up. of course a warrior in epic cloth would still look good, and it didn't factor gems or enchants or talents etc. still i found it very useful. this is the closest i've seen since, so i would like to request some sort of party/raid support, unless someone was to remake gearrating for LDB.
