The other day I had an idea based around the elements and primaries since the Zhalo is the only primary with one. What if they made it to where you could get a certain crystal or item from one of the elements and infuse it into your weapon. So you could have a weapon that was just bare but you could infuse a crystal into it and change it into a void,arc, or solar weapon. The other part was that you could infuse different crystals to change the element of the weapon ,but you could only do it three times to a single weapon before it stuck to it. You could get them through weekly stuff or random drops in heroic and nightfalls. What do you guys think? I was just kinda sad at the lack of elemental primaries. But this could go for any class of weapon.
