That's not exactly true. It's really Bungie's fault because there the ones that programmed the nightfalls to have random burns. Plus you don't see a lot of people running around with Zhalo in the crucible, Also most of the changes you mentioned were PVP FOCUSED. I don't see a lot of people using Zhalo in pvp or pve. Unlike Fatebringer it, isn't top choice for pve. It's also EXOTIC. so you have to make the choice, do you either want Zhalo and give up something like plan c or Bolt Caster
