I'd like it if they would have made the raid primary exotic an ongoing upgradable item. Id like it if they had implemented a way to upgrade not only the damage to be scaled as it was before dlc, but also the damage types. And after HOW, you'd have a weapon with all three damage types. If you could use the crux to change the damage on the vex instead of making the horrible necro, I think it would be awesome. Nothing special, but it would be really cool to have that option on what's supposed to be the rarest weapon in the game. Plus it would make VOG relevant for those who don't have the vex.
