Cores should not be in infusion period, I play a LOT (5000+ hrs in the franchise) and it is just too punishing. I want to be able to run whatever I want without stressing the fact that I NEED to do bounties in order to get cores to progress my gear forward. Add in all the other bounties, pursuits, etc and I will never have time to participatein other activities. That isn't including the fact that you only have 50 spaces to store those things!
