I have found specific Equipment to be one of the most difficult things to get in the game, being that it is 100% random (either collected or Researched). In fact I spend over 17h just trying to get enough equipment to make 3 Legendary, just to waste them to make 1 nearly useless XSTN, just to get through the Barrier. I propose an Equipment FACTORY, just like the turret factories, but makes blueprints for Equipment. So I can get a specific piece of Equipment & just mass produce it for my fleets (or Research).
