After new content gets released I hope any notes are vague. After 5 years of playing WoW, I don't want to know every little detail of who, what, when, where, and how the patch effects the game. I want to be skilling up WC and bam, new receipe, arrows? This is a game of discovery, I want to be the first to stumble across a 3 headed llama with frikken laser beams on their head, not have patch notes explaining HP, location, and 13 screenshots with all possible loot drops.
I think the community should be making the notes, not the devs. If the community decides to make a wiki, or keep trade secrets, then let the community decide.
There are enough games that spoonfeed you info, I'd like Xsyon not to be one of them.
