I never heard they are going to upgrade it. I used it a lot early on in Destiny, but it's really not that good imo. I never use it anymore because there's several legendary LMGs that have similar or even better stats depending on the roll (Deviant Gravity-A and Against All Odds). If you don't have vault space you might want to delete weapons you don't use. I'm not going to tell you which guns to dismantle that's up to you. The only exotic I no longer keep in my collection is Super Good Advice. I am thinking about deleting a few more myself including Thunderlord and No Land Beyond because I never use them.
