I'm going to use my first golden key just as soon as I find the box. I'm going to sign up for the Shift community thing also and save that key for a later time. Probably some time in my 30's or maybe wait for the 40's.
I'm just figuring that by the time I reach the 30's or 40's I'll already have something that outclasses a random purple. I would also hate to wait until the 30's or 40's and get a shotgun for my character that solely uses combat rifles...or...even...a...pistol...(shivers...eww)
