The Optimization Station should not work on Exotics and should not update pass your library stat. So if you do not have a stat maxed out in your library you can not optimized pass that stat you have in your library. To me this will still make farming a thing but let someone still max out stat and library. It's progressive.

Exotics has the reconfiguring letting people max out exotics just takes reconfiguring out the game and grinding for exotics out of it. So please do not allow exotics to be use on the optimization station
