Well, they said you can find a random sword, and have no idea what the hell it does. Does that help?
Did they confirm this? If this is the case, I want to find weapons that do terrible things to you if you don't know what you're doing (thinking back to a D&D campaign I was in once with a sword that randomly changed your race every time you hit something with it)
For the most part, I don't like particle effects, but I'd like something more than plastic wrap. For a fire enchantment, for instance, I'd like a sword that looks like it was freshly tempered. For a frost enchant, I don't want it to just drip fog everywhere, but simply have a coating of shiny ice on it, and some frost specks to make it actually look frozen and not just wet. Stuff like that.
