My luck is finally turning around, at least for a few hours today.
I just got 6 legendary engrams to drop in the last 2 hours, one of them being an exotic rocket launcher named TRUTH.
Upgrades
Soft Launch: "Less recoil. Penalty to range."
Hard Launch: "More range and impact. Increased recoil."
Warlord Veniers: "More range and impact. Increased recoil."
Grenades & Horseshoes: "Rockets from this weapon will detonate early based on proximity to targets."
Heavy Warhead: "This warhead considerably improves impact, but fewer can be carried in reserve."
Fieldwire Fragments: "Charged fieldwire shrapnel increases impact."
Colony Warhead: "These small warheads have swarm intelligence, allowing you to carry more in reserve and enhance impact."
Prototype Trueseeker: "Rounds fired from this weapon seek their target aggressively."
