I know it won't happen but I hope they just ditch that REQ pack shit completely. It didn't take long for me to notice that it took two or three hours of gameplay to get one gold pack, which would MAYBE give me one piece of an armor that I wanted, but most of the time it was just fucking trash.
It was a lot of fun working for achievements in Halo 3 for armor, and it wasn't too bad getting in-game cash to buy armor in Reach. I don't remember (or care) how it worked in 4, but the method of playing hours on end in Guardians to maybe get the set I want was a pretty big turn off, but I guess that's just the story of games these days in general...
