But its not progress throttling... You progress in light level without infusioning.... The only thing Infusion does hinder what you can use forcing you to grind boring content for cores or just use any old crap that drops at a higher light from milestones this is not progress throttling and it does not offer a feeling of progression as Bungie insists as again the milestones drop at a higher light which is how you progress and has nothing to do with enhancement cores.
