It seems no one brought it up yet, so I will:
Increasing L.O. and Isotope Consumption has simply to do with @CCP_Fozzie is a friend of Alliances who do Rorqual-Mining all day and everyone knows that Industrial Cores eat the Heavy Water and thus he want’s to make sure the other parts stay valuable in order for HW prices not to break through the ceiling, because that would be sad for said Rorqual-heavy Alliances.
Job well done. Thanks for being there for all of EVE CCP. You are really not giving anyone the impression of doing a job for one or two Alliances and this whole thing is totally motivating for the player base. Keep on doing things just like you do them now.
