I saw in a comment that you bought a new controller, I did this as well no luck. I had one of the white PS4s that was sold with a copy of Destiny and I first started to notice it with Crota when I would try to smash him with the sword. I would just stand there doing nothing till I hit the trigger again. I was at Gamestop figured I would just replace my controller again, my luck just got a bad one. They had one of those mod packs that add paddles to a normal Dual Shock for 10 bucks so I said the hell with it and figured I would try that first. This turns off the Bluetooth and the controller data is sent via USB. Sure enough no more dead trigger pulls and everything was back to normal. Due to my Bulldog freaking out while trying to get his ball out from behind the TV I was forced to buy a new PS4 and have not had the same problem that I had with the White PS4. This whole thing leads me to believe that something went wacky with the Bluetooth card in my PS4 because like I said if I used the mod it worked just fine and when I got a new PS4 never had the problem while using the same controller minus the mod pack. Oh for info this is the mod pack I got. https://www.amazon.com/Collective-Dominator-Controller-Adapter-playstation-4/dp/B01L8QHXJA I guess it can do stuff that is rather unsavory, I just used it so my damn controller worked right. EDIT: I added a quick video I did showing what would happen with the sword. After getting that MOD pack I tried for like 20 minutes to get it to happen again and it never did.
