Hmm.. I have had over 20 different shaders so far.. have had enough that had to discard many of them just so would not fill up my vault with them. Gotten several from strikes and several from playing in the crucible.. so there more than just what she sell so is not really a big deal that they does not change them that often yet. Plus the game has only been out a month.. having lots of shaders is not a important issue that needs being fixed right away.
