There is a reason and just keep a look out for updates but a while back bungie has been looking into ways to make pvp more better and one of the ways was to in comp when you lose a match the rank score won't go down if this is being put into the game which would Make these weapons more easy to obtain then that's why the two handcannons are being hit and who remembers g horn the moment that weapon was easy to obtain it got a huge nurf and the same with redrix the gun is not as good as it was when it fist appeared all because it was much easier to obtain.
