I've begun creation of a website that lists gear for each class and ranks it, you will find it here: Rift Hero.
So far only the mages and warriors have active lists because no one (to my knowledge) has worked out weightings for the other classes. At this point I have to give a massive nod to MealRain and Archyface as they did all the heavy lifting with the math (and providing xls document versions), I am merely creating a web alternative.
Right now the lists for warriors, rogues and clerics are empty, I am looking for someone (with a good post history here) who would be interested in the monotonous task of entering all the gear they can find. The weightings are in for warriors so their lists will sort themselves, I just need a data entry monkey willing to sacrifice a few hours for the good of the community.
More importantly, has anyone done weightings for the clerics and rogues yet? Once I have those I will open up their ranking pages and fill the database with their gear.
I hope the site is useful, and would appreciate any feedback you have or bugs you may find.
