I think it would be good to have orb generation be associated with our ghost shell. Thematically it feels right that our ghosts are the link to a power like that, being of the light and all. Gameplay wise it would be just fine. gives more value to our ghost and will give a more strategic choice to some ghost mods. I don't really care about most of the mods unless I farm materials, glimmer, armor rolls etc. It would make my ghost feel like more part of my load-out rather then just flair that has some utility. As an off note, I seem to remember a few years ago the lead weapon sandbox design (or whatever his title is) mentioned that weapons have capped out on their potential given the amount of memory that they take up and that orb generation takes up a large portion of that memory. I read that as not only potential perks and such but also how many things we could have in our inventory; logistics of vault space comes to mind.
