With the addition of random rolls, gear has far more stuff about them. I don't think it's about just infusing shit aimlessly to get to 600 quick as we can.
Whilst I enjoyed my infusion plan over the last few years, that doesn't mean it's right going forward.
Don't forget I'm saying I agree it needs changing, which they have confirmed something will happen, just doesn't need removing completely. Infusion in games should be a decision, not just an action.
Maybe stick a weekly bounty from Spider for 10 MW cores. Or give rewards after completing a Nighfall for 5 MW Cores. That's a better solution.
