Forerunner Fragments, Crystals, and a Usable Ideas

[Terran]

Are these forerunner fragments you mean? Because if there's more options for earning them then it really trivializes the amount. I already have like, 600+ extra and I buy every cool thing that comes out, including one or two godlikes. I barely do quests too - I'd like to see this currency be other than Forerunner Fragments. Maybe a special shop that can sell PvE weapons, bonuses, runes of looting, PvE-trait adding crystals, etc?

As it stands I do quests pretty lazily and have loads of fragments, and I'm sure I'll get more.
I like the crystals! But nerf SAG first, ty.
