[quote]Heroic Patrols dont give red border weapons[/quote] They do - it's intentionally been nerfed. You used to be guaranteed a weapon from heroic patrols but during Lightfall (specifically Season of the Deep) they were added to the heroic public event loot pool so Bungie removed the guarantee and filled the loot pool with world drop items as well. So now you've got ~3/4 layers of RNG for it - getting the heroic patrol, it actually dropping a Neomuna weapon, it being a weapon you need, and it being red bordered. Make sure you've maxed out Nimbus for the engram upgrade. Unfortunately the guaranteed source from the story missions was retired with the launch of TFS.
