There are many people in my guild that have spent the time to be some of the best crafters in the game and yet all of the end game set ups are dropped sets.
I think that making Ebon, Hircine, and Worm craftable would be a nice bone to throw to all the crafters that have worked so hard to be the best crafters. These are sets that
PVE folks wear for trials, but probably not for their every day set up. It is basically an "extra set". I know that I have farmed the crap out of COH and it is pretty tough to get
sturdy Ebon, which is the meta now. These sets used to be Bind on Equip and that is what they should be.
