In fact, this was really the point. Several melee specs (and Marksman hunters) had begun to focus on armor pen at the expense of all other stats. Gear without armor pen was being passed over and gem sockets were increasingly being filled with just this one stat. While every spec has stats that are more valuable than others, this one felt like it was starting to trump everything. Not coincidentally, characters stacking lots of armor pen were starting to do more damage than their peers and more damage than we were comfortable with.This change is largely for PvE reasons, though we won't cry at all if melee damage in PvP drops a little as a result.We're letting you know now so that this doesn't feel like a stealth nerf, assuming it goes live. While you might disagree or be frustrated by the change (though I also suspect it won't come as a surprise to many players), we ask that you try and keep your response to something appropriate for these forums.We've seen WoW used for a lot of research, from epidemics to anthropological fieldwork, but this is probably one of the craziest and one of the most helpful ways to use it. Psychologists at the University of Miami and the University of California, Irvine have been studying how guilds and groups form in wow gold in the hopes that it'll help them figure out how gangs form in real life. It's very interesting.Unfortunately, they are full on potential but still pretty short on conclusion yet.
