I still don't see why they haven't implemented an item exchange yet, like they did with shards. Why is there not a transfer from armor to weapon materials (and vice versa) for a nominal fee of glimmer? That way no matter which way the engram ratio is skewed on a person they can get the materials they need. This also ensures they still grind for those materials and earn them, but aren't screwed by rngesus despite that fact.
