To take some of the heat off of floon here, I think you hit the nail on the head. WE as a player base should determine what's important. You are confusing WE with YOU.
I'm not trying to be mean or belittle your desire for this. I know how much work went into getting those armor sets and I understand the frustration of seeing them essentially just fade away into nothingness . The truth, though, is that it's an incredibly small subset of the customers who want this, and you're seriously comparing it to the undertaking of the development of Moria?
Floon, keep on keeping on. You are doing a fantastic job. I doubt that you hear that often enough. I truly respect you for your willingness to answer questions in these forums when regardless of the answer you give, 50% of the community winds up berating you for it. And the work you're doing on textures and new looks for gear has made me incredibly happy.
My Champ has been wearing the same cosmetic outfit since level 30, and for the first time I'm finally finding stuff that I'm collecting to make a new one because the dwarven armor styles in Moria are just that freaking cool.
