Starved for content? Between farming luther for atlas units, MBVR for Ult boosters and skydance, Ultimate Ship infiltration for crack and piper when it pops up there's honestly plenty to do. It just sounds like your not really willing to get your hands dirty and grind. People are doing runs of all of these pretty regularly on ship 3 block 1. Honestly im sitting on like 100+ ultimate boosters and Two liberate weapons+ full 13* units and i decided id just prepare the stuff needed for a puras Bow and Double saber. Theres always somthing to do its just a matter of if you want to grind for it or not if im being completely honest. Even when ive got nothing to do i just see what my friends in my alliance/friend circle are up to and join them and just have a fun time.
Heck You can even do Endless quest or solo pd or Solo Mom+deus, Masquerade or Phaleg for some more challenging content. If none of this interests you then just play another game.
