If you need a heavy or stuck trying to level up the Eris quest helps for a heavy. I got mine at 1223 after been stuck at 1220 for a minute! Start the “memory quest” by heading to Eris..... Get the “Luna spelunkers” bounty and start there. It will guide you through the rest and basically it’s lost sectors. Sorrows harbour and waves gives progression on bosses and ads to kill.
