I have 75 currently, will be at about 80 or 81 when HoW drops. That's good for 8 rank ups of whatever faction I feel like using them on. That being said, I may opt to use them on Dead Orbit, as they are the only faction that I do not have a shader from and I want to get at least 2 from each one. Currently I'm sitting at 2 FWC(Nineveh 8611 and Carthage 0100) as they are my faction of choice and 1 New Monarchy(Themisto).
