For a while now I've been wondering why there are no blue/purple drops in STFs. I was told that it was to prevent people from farming them. That makes no sense at all considering you could just go to a DSE in Gamma and farm just as easily, if not more so, than in any STF.
So, basically, I'd love to see blues/purples dropping in STFs, even if they have lower drop chances than they do outside. Rolling through Infected/Cure/Khitomer and only ever seeing blues on minibosses and purples on main bosses, ever, seems a bit silly and too formulaic.
