Normally we cry when we get a legendary from a Nightfall, but I got the Devil You Don't from last week's nightfall and I must say it absolutely tears through and destroys everything. Loving the gun, destroys everything in the Crucible (was using it for IB today) and then it also still does great in pve as a purple, though Hawkmoon/TLW/Thorn/(fatebringer?) are probably better. However, altogether I would rate the gun at an 8.5/10, definitely going to love using it. So powerful they had to boost it down to 5 rounds of awesomeness per reload ( ͡° ͜ʖ ͡°)
