I bought my first one from Xur when everyone shamed me for buying an exotic rocket launcher until I leveled it up and fired it into the loot cave. Since then I've found two more and helped others nightfall, Crota, Atheon and strike their way to getting one. Yes seeing it pop up or getting it from a purple engram is amazing but seeing day one players who sherpa and assist randoms finally get one or three is just fantastic. So I lift my heavy ammo synthesis to Heimdall as we all unleash hell and begin Ragnorok for Oryx and his Taken army.
