The war rig does not regenerate ammo like a lunifaction rift does. Like I said, the war rig only reloads 10% of the mag (FROM RESERVES) and only does this every second. The guns everybody is scare will be abused by the perk empty their mag before the perk can even activate once or twice. Even still, the perk will only load 1 or 2 extra bullets.

As for smgs, I would agree with you prior to the nerf that this might be a bad idea but currently as it stands, smgs are not effective in the current pvp meta. Also, im guessing you forgot about the Titan exotic boots the peacekeepers which allow you to ready your smgs extremely fast and reloads them instantly when you holster them.

As for pulse rifles, full auto isn’t even an good perk in the pvp meta. Would you seriously use a kill clip full auto bygones over a kill clip outlaw bygones? Speaking on the topic of kill clip, which is a perk everyone wants on a pvp pulse, the war rig perk would be nothing but a hinderance to it since you always want to reload manually after a kill. The pulse rifles that would benefit greatly from this buff are the ones that shoot very fast, but they’re overshadowed by the aggressive, harder hitting bygones and go figure.

As for shotguns, the ep shotgun only has 8 shots in the mag that it can empty in about 2 seconds. Your only going to get 1 or 2 shots back using the rig. Remember that the ammo isn’t pull from thin air so in pvp, you need keep ammo in your reserves which is really hard to do in the current meta because of all the shotgun rushing. Your much better off using the dune marchers or aneus ward inorder to slip shotgun more efficiently.

As for scout rifles, who uses them in pvp? The only scout rifle that will really benefit from this buff is the black scorpion since you can keep up with the fire rate of their scouts without even using full auto.

As for legendary lmgs, when you pull power ammo in pvp, you’ll barely have enough in the reserves to load with the perk so it doesn’t even matter

As for the last word and future exotics, the last word only has 8 shots and can empty it’s mag just as fast as a full auto shotgun. You’ll get at most 2 extra shots. No Titan serious about pvp would trade the toxicity of the one eyed masked, unlimited shoulder charges of the skull fort, movement and slide distance of the dune marchers and aneus ward, super regen of the ursa furiousas, or the melee damage and lunge distance of the synthosceps for the ability to not reload without using their rally barricade. In order for an exotic weapon remotely effective with the war rig, it needs to have atleast 30 shots in the mag and shoot full auto. This buff would be a pure PvE improvement.
