I made a post about this idea but since it didn't get much traction I'll add it here Seeing that elemental primaries are being left behind.  I thought up a good way to bring them back into year 2.  Just like the “No Time to Explain” exotic bounty forces you to go through the Vault of Glass, I believe that infusing elementals into new weapons should do the same.  My idea behind this is to have you collect the Elemental primaries from both raid and as well as other items from PoE in order to infuse that element to the new gun. For example.  I want to infuse ARC into any new primary, you would need to collect a raid weapon from both VoG and Crota’s End in order to infuse it.  Collecting a FateBringer OR a Praedyth Timepiece, as well as an Oversoul Edict OR a Fang of Ir Yut.  The Last thing you would want to collect would be a weapon core and a Etheric Light from PoE. By collecting all these pieces, this will allow you to infuse ARC into any primary.  Not only will it make old Raids and PoE matter again, but this will also fix the issues with people having problems with elemental primaries being left behind. Tell me what you think
