This is something I've been mulling over for the past few days, but as much as I enjoy them, sidearms aren't special, and shouldn't be considered special weapons for that matter. Adding them as a separate category, similar to artifacts, would allow for greater build diversity. ...this might take a minute to explain... Special Weapons in Destiny are the One Hit Kill weapons that you just don't have ammo for all of the time, the differences at the most basic level is the ideal ranges they are used to engage. Shotguns, fusion rifles, snipers. Sidearms really don't fit, they act as a counter to all of them equally well, with the right tactics and situational awareness, but they don't have that special one hit kill capability to make them feel special. A sidearm is a last ditch weapon, used when you got nothing left to use, at least in other games, and as glorified in the movies. We have pistols with various magazine sizes, and the power of a reanimated Last Word. This should not be the case, the are becoming a meta unto themselves. Fixing the carryover ammo issue is a step in the correct direction, but the game can go one step further by separating them and having every guardian carry a sidearm. Technically, I have zero knowledge of the game engine, but that not withstanding, I believe the mechanic is not currently being used in the game, and should not interfere with much of anything. It would revolve around the use of the Y button (triangle). As it stands we have three weapons and two functions associated with the Y button. Equiped weapon, press Y to switch to a unequiped non-heavy weapon, and hold Y to equip heavy weapon. Adding a function to a double press of the Y button would allow for my above suggestion to removing sidearms from special weapons. Starting with a primary weapon equiped, pressing Y would act like normal and switch to a special weapon. As your one hit killer runs out of ammo, you can quickly double tap Y to switch the special weapon for a sidearm in the choices given to the single Y press function. With a sidearm now equiped, pressing Y would allow the guardian to switch back and forth from a primary to the sidearm. Now having found some special ammo, but out of primary let's say, with the primary equiped double tapping Y would switch it with to stowed special weapon on the single Y tap function. Holding Y would be unaffected. Just some thoughts and wishful thinking. Maybe it's not to late for Destiny 2, by the way when is that coming out?
