This post is basically a point about weapon diversity and some questionable things. The best way to explain is to just go over these kinds of weapons. Elements are not being considered here. Adaptive Frame SMGs: I'm not sure why we don't have any non-sunsetted SMGs of this type. It was a perfectly-viable weapon type. Yes, Lightweight Frame SMGs can kill faster if you can land mostly precision shots and they're both 900 RPM, but this kind typically had better stats that made it more consistent and forgivable. Trackless Waste was one of my favorite SMGs back during Forsaken. There were also many players that enjoyed Exit Strategy. Why is this kind of weapon being discontinued? I don't see a good reason for that. Perhaps in the next couple of seasons we could see this SMG Frame revived? Aggressive Frame Fusion Rifles: A.k.a. 'the Warden's Law of fusion rifles.' Only one weapon of this kind exists and that is Coriolis Force, which has a very questionable place in viability right now. It has the same charge speed as Adaptive Frames and it hits almost as hard as High-Impact Frames, but it's a horizontal burst with poor range performance as half of the burst tends to miss more than hit. And the burst shoots all projectiles out at the same time, so being that you can still aim while you have to charge it, stability isn't really necessary either. It really doesn't matter if you spec out in range or stability on this weapon, it doesn't really feel that much different. This type of fusion rifle might need buffed if it is to be expanded on. Perhaps reduce the damage on the shots of the weapon, but also add a second burst that follows up on the first one? That sounds "aggressive" to me. Might have to tweak the charge time if Bungie goes that route though. Precision Frame Heavy Grenade Launchers: Think of a special Lightweight Frame grenade launcher, but reduce the velocity, increase the damage, increase the mag size, make it a heavy weapon and you have this kind of weapon. As far as I'm aware, this type of weapon has been completely discontinued since other grenade launchers seem to out-perform this kind. These ones do have a bigger blast radius compared to other ones though if you are good with controlled detonations. But I don't really see this kind coming back unless there's some weird exotic that's going to be made out of it. Double Fire Hand Cannons: Warden's Law basically. Discontinued due to technical issues from what I hear, but I would still love to see this kind of weapon come back. Maybe people just need a little bit more creative juice. Maybe something needs figured out with the spread and damage... Lightweight Frame Auto Rifles: If you haven't noticed or heard, this kind of weapon surprisingly exists. Jiangshi AR1 is the only one of its kind and it's an uncommon/green-rarity weapon. It's a 450 RPM just like Precision Frame auto rifles, but without the Precision Frame benefits and instead increases movement speed. We'll... say that it's discontinued. I don't even know if you can get it to drop anymore. I don't see this kind coming back. I personally want to see more Adaptive Frame SMGs. They can be used competitively too. It would be more interesting than seeing Shayura's Wrath and some Multimach CCXs the majority of the time when SMGs are used.
