I think that kind of ranking is kinda bs because everything depens on the team you are using this ninja in.
And... ninjas with passive barriers as 2nd tier? Srsly? But what if you running a team that can survive bijudama and can do good dmg after that...? oh wait... it can't because your dmg will lack barrier's buff. All ninjas with passive barriers are tier 3 at best imo if you rly have to do that list. I wouldn't agree with most of those ninjas in those tiers tbh (BD as 2nd tier and Yamato 1st hurts my eyes the most).
