After getting the catalyst done I never went back to it. Ammo is too low, demolitionist intrinsic feels bad on fusion, the grenade eating alt fire is strong but not worth using a grenade for it to just shoot once. It should be a chain effect of eating grenade to big boom get grenade back on kill rinse repeat, based on subclass you get a verbed explosion to coincide with it. With the changes to everything stat wise and exotic wise, there is a lot of work to be done going through every single exotic weapon and armor. They will all need a rework at this point, and how Bungie is handling this is by 15 exotic armors per 6 month cycle and 20 weapons as featured, that's about 5 years of time to rework and feature everything all over again. But what do I know, I'm just a guy who plays the game 🍻🫡
