I'm torn on the Ogryn idea. Part of me would love to play an Ogryn, but another part of me is certainly hesitant due mostly to how GW has far more often than not portrayed them as stupid to the point of being nearly handicapped and the comedy relief.
I would like to see a Sniper career and also a Scout career. I'm not sure they need to be the same career with options for branching into one specialty or the other or two seperate careers.
