I like the concept. It's the very beginning steps of what I believe will expand and be built upon throughout future updates and seasons. Imagine 3-4 seasons from now when there is a vast amount of weapons to craft. The process of getting just the right weapon will rely less on grinding raids or engrams and a whole lot of RNG will be no more. As for grinding the weapon levels, I agree... after grinding two weapons to lvl 15, I lost motivation to do it again. Maybe there will be a feature to spend currency of some sort at the gunsmith or forge?
