Damn. Thought you hit rank 70 on one character, not all three combined. If we're counting combined rank I'm 48, soon to be 49. So far I've gotten 2 Bittersteels and the jump ship. Got the jump ship on my hunter in the early 20s, Bittersteel dropped for my hunter around low 30s, then again on my titan the very next day (she was at rank 6).
