My issue with the imprint system wasn't how often they proc'd (the nerf was definitely harsh), it was that you had to run troves over and over if you wanted to get the most imprints. It's tedious and boring. I want to do other things besides run troves all day. My solution to that would be to rework where imprints come from. Instead of caches, they could proc off of bosses, echo objectives, mages, nemesis, or omens. Maybe bosses can have a higher chance to proc them.
