Actualy the low vault space was a good thung in the long run, it meant that the total number of exotics and high end gear in game was capped and that people would have to realy trim the fat, this however isnt clearly apparent right now because the number of good weapons worth keeping just isnt high enough yet, we would need hundreds and the ability to ramp up light levels on gear in order realy start to see differences in character looks and play stlyes.
