I've finally decided that I'm going to chime in here, since this was something that's been on my mind for so long, and it's nice to see the discussion is finally getting it's time to shine. I believe that Masterwork Cores don't have a place in Infusion, and should instead maintain a key role in masterworking those weapons you want to bring into the end game. Infusion to me is a process that brings the equipment that you enjoy all of the time up to your current light level, when I get a prime engram with another Prodigal chest piece with +5 above my current LL, I don't want to use it, I want to use my Iron Banner chest that is currently 15 light below. It's not a tool that needs to have such a major road block to prevent you from bringing your favourite set pieces up to par/ Masterworking your gear is the end game effort that MW cores should have a sole purpose in, and the amount that it requires to bring everything up to top tier, is in a good place. I believe masterworking equipment is the only thing I should be accumulating MW cores for, for when I finally get that god roll weapon that I want to keep on me at all times. Let's talk in terms of investment and the power fantasy. I've invested my personal time for 12+ months in Destiny, I'm no longer a blueberry. I don't want to lose my power fantasy every time the max light goes up in another season, I want to keep being the same badass that I was when I hit max light 8ish months ago. Infusion lets me do that. By keeping MW cores in the infusion process, I have to go back to scrounging things together for 50 light, and my stuff goes into the vault for that time while I squirrel away. Masterwork Cores don't make Infusion meaningful in its current state, it makes it a hindrance to the power fantasy at the moment. Making it easier to earn Cores doesn't fix that issue, it continues to hinder the fantasy. Edit: I've realised that I've said Masterwork Cores instead of "Enhancement Cores". Call a Dog a Cat, it doesn't make it a Cat.
