Its a constant battle in the game development. New boss items get stronger to the point of surpassing the strength of old UN items. The solution to this? We always see a big jump in the strength of ALL UN items. including the ones that are currently for sale, and did not need updating in the first place. What i would like to see... A UN section in the workshop. Where players could add a few items aquired in the game, along with something like 5 UN to update their old and busted Un items to brand new status. lol. I know the folks down at kano are going to read this and go... "do you know how much work that would be?" I wouldnt expect to see this idea for a long time. but this is the kind of update we really need in the game.
