You dont even NEED cerberus thats just side note you didnt adress any of his main arguments.I think both of you have quite unrealistic expectations of things. For example, the availability of Cerberus. Only now am I starting to see some Hanumans, and that thing has been out for... seven months now. Sure, you can keep rerolling until you find one for content that matters, though.
Thats the point you dont even need herc and SS but its still a perfectly viable option no clue how its ''unreliable'' in any way shape or form.Another thing, why use unreliable SS, and/or use Herc in a Fire team, slowing down your entire team in this era of Shingen? Fire in particular has fairly ease access of a Phantom Lance Grids, something that Shingen particularly enjoys.
Herc cant be used because shes slow but Ama is not??
Also theres no way someone running a null grid needs debuffs for solo content so thats a moot point.
