Some time ago I used to get up to 1-2 new blueprints after killing Fabius/Iron Maiden. Now i have to kill ~15-20 Nemeses just to get a single one (Fabius/Mooislike/Valdaran/Behn’Jahr/Cubacabra/Reaper).
Does the chance of getting new blueprints decreases with every new learned BP or do i still get duplicate BP’s, that i can’t see? I mean should I stash “useless” blueprints and wait for better one or learn as soon i get a blueprint without having troubles farming them in the future?
Learn BPs as soon as you find them. The chance of rolling a BP does not decrease, but if the rolled BP is a duplicate (ie you learned it already) GD will do a few rerolls in an attempt to drop a new one, if after 5 or so rerolls you know all the ones GD ‘rolled’, no BP drops, so the fact that you know most BPs makes new drops rarer.
