I use the Catchmoon because it's the only secondary I have currently that keeps me alive in Sorties and other high-tier missions. Sure, It's insanely powerful, but sometimes you need a powerful weapon as a last resort to survive. I've tried out quite a few other secondary weapons, and Catchmoon is one of the only ones I've used so far that has actually worked for me in a way that makes me want to keep it after ranking it up. It's my go-to for all sorties because it doesn't take me forever to wittle an enemy's health down, unlike others I've used. This nerf affects me quite a bit.
