Except that if I make one of my Sims a hacker, it can overclock any computer and that's supposed to improve performance or something.
But yeah, somehow we're going to get "Overcloaks" which are COSMETIC cloaks that you can put over your normal cloak. So you're still powerful, but you're stylish too.
I approve of this most heartily.
MMO Champion mentions the shown cloaks are rewards for retaking the gnome and troll cities, specifically, but Blizz might have more plans for the mechanism. (Loosely paraphrased.)
