My opinion, all primary exotics should have the ability to be upgraded with an element if they do not yet have one (e.g. Vex, Necro, Zhalo). 2500 glimmer, 25 weapon parts, Exotic shard x1, and an elemental core x1 that drops ONLY on the hard end game activity, RNG, as either solar, arc, or void. The gun, once upgraded emits a chroma glow matching the damage type from the barrel. This adds enough reason to work for that end game grind, while also giving reason to do it enough to get those favorite primary exotics upgraded. Any ideas or suggestions or salt, have at it, but something needs to be done to once again make people feel like there's a reward for getting through the raid.
