Do share, why don't you use them? And I'd rather have more specific reason than "I don't like them" (which is a valid reason ofcourse), because I'm curious why don't you like them.
Thank you!
EDIT: Typo, and thank you for feedback. :p

I just started using one for grimoire points haha... I've found you can actually shotgun most bosses, there's just a trick. You can even shotgun Rockets McD. When he's on the ledge just crouch down right up next to it and his AOE won't hit you. Then when he's walking you can run in, shotgun, and double jump out.
