If you're looking for databases, check out the one we have at
AskMrRobot.com. We have 2 unique things to offer
1) We are constantly verifying data to have the most accurate database out there. For example, we're the only ones right now with the correct listing for campaign gear (we removed the variations that don't exist). We also try to keep sources up to date... for example, we show that old champion gear is 'retired' from the game.
2) Soon we're adding a community feature that will link to relevant articles (written by other people) on item pages. For example, if you're looking at a war hero piece of gear, how nice would it be to have a few links to pvp guides, or pictures of that pvp gear set
